Book Synopsis Prognostic Health Assessment of an Automotive Proton Exchange Membrane Fuel Cell System by : Christopher J. Rukas
Download or read book Prognostic Health Assessment of an Automotive Proton Exchange Membrane Fuel Cell System written by Christopher J. Rukas and published by . This book was released on 2013 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Proton exchange membrane fuel cells are a promising technology for the automotive industry. However, it is necessary to develop effective diagnostic tools to improve system reliability and operational life to be competitive in the automotive market. Early detection and diagnosis of fuel cell faults may lead to increased system reliability and performance. An efficient on-line diagnosis system may prevent irreparable damage due to poor control and system fatigue. Current attempts to monitor fuel cell stack health are limited to specialized tests that require numerous parameters. An increased effort exists to minimize parameter input and maximize diagnostic robustness. Most methods use complex models or black-box methods to determine a singular fault mode. Limited research exists with pre-processing or statistical methods. This research examines the effectiveness of a Naïve Bayes classifier on determining multiple states of health; such as healthy, dry, degraded catalyst, and inert gas build-up. Independent component analysis and principal component analysis are investigated for preprocessing. An automotive style fuel cell model is developed to generate data for these purposes. Since automotive applications have limited computational power, a system that minimizes the number of inputs and computational complexity is preferred."--Abstract.

Book Synopsis PEM Fuel Cell Low Flow Rate Diagnostics by : Amir Masoud Niroumand
Download or read book PEM Fuel Cell Low Flow Rate Diagnostics written by Amir Masoud Niroumand and published by . This book was released on 2009 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient, reliable, and durable operation of Polymer Electrolyte Membrane (PEM) fuel cells are key requirements for their successful commercialization. One way to achieve this is to use diagnostic tools that can be used during product development and operation to satisfy these requirements. Such diagnostic tools are introduced in this thesis. We introduce the ratio between call voltage and cathode output pressure oscillations as a diagnostic tool for the PEM fuel cell cathode. We show that for our system, these oscillations have similar frequency. Therefore, we propose using the amplitude ratio and phase difference between these oscillations to understand fundamental processes in PEM fuel cells. We use the measure introduced above to design a signal based Fault Detection & Isolation (FDI) algorithm to isolate anode and cathode low flow induced faults during operation. We show that cathode flooding corresponds with an increase in the amplitude of voltage oscillations. Cathode starvation occurs at a cathode stoichiometry that is a second order function of the fuel cell current density for our system, while anode starvation occurs at a fixed anode stoichiometry. We use these measures to design diagnostic residuals, along with a boolean diagnostic logic, to isolate the low flow induced faults. We then examine the robustness of the proposed algorithm to changes in current, pressure, temperature, and humidity operating conditions. Finally, we introduce a sensory vessel capable of measuring the two phase flow as it exits the fuel cell. Using this vessel, we detect two different modes of liquid water retention from the cathode. The first mode is periodic and imposes similar oscillations on the fuel cell voltage, while the second mode corresponds with a spike in the cell voltage. We conclude that the source of the first liquid water is in the Gas Diffusion Layer (GDL) and catalyst pores, while the second sources is in the cathode flow field. The pressure-voltage oscillations and sensory vessel are diagnostic tools that can be used to provide fundamental understanding of processes in PEM fuel cells, while the FDI algorithm can be used during operation to improve system performance, reliability, and lifetime.
Book Synopsis Contribution to Prognostics of Proton Exchange Membrane Fuel Cells by : Dacheng Zhang
Download or read book Contribution to Prognostics of Proton Exchange Membrane Fuel Cells written by Dacheng Zhang and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of the energy transition, fuel cell becomes one of the promising alternative energy sources. Recently the spotlight is on fuel cell systems research, and more particularly on Proton Exchange Membrane Fuel Cell (PEMFCs) which is one of the best candidates for both stationary and transportation applications. Even if this technology is close to being competitive, it is not yet ready to be considered for a large scale industrial deployment because of its limited durability and reliability. Prognostics and Health Management (PHM) is a recent approach to manage and possibly extend life duration of technological systems. Prognostic techniques can provide an estimation of fuel cell State Of Health (SOH) and a prediction for their Remaining Useful Life (RUL) to help the manufacturers improving fuel cell performance and managing its lifespan.The objective of this work is to develop prognostic methodologies for the RUL prognosis adapted to the complexity of PEMFCs. Indeed, the PEMFC is a multi-scale and multi-physics system, and various challenges are faced:1. The definition of SOH to build a degradation indicator.2. The coexistence of both reversible and irreversible degradation phenomena.3. Taking into account different deterioration causes and effects of operating conditions.In the first part of our work, we conduct a state of the art analysis on PHM for PEMFCs, with the aim of proposing a SOH definition and building a degradation indicator for PEMFC prognosis purposes. And since PEMFC measurements are scarce, the state of the art on Lithium batteries, other electrochemical cells, is also explored.In the second part, we develop a particle filtering based prognostic algorithm for PEMFC, based on output power measurements. The first results show that the prognosis algorithm is disturbed by the existing reversible degradation. However, the irreversible degradation can be estimated thanks to characterization tests, such as Electrochemical Impedance Spectroscopy (EIS), which is applied from time to time. We propose thus an adapted & extended prognostic algorithm to take into account both health indicators: the output power degradation and the SOH degradation estimated from EIS characterization. The performance of the proposed algorithm is evaluated by different prognostic performance metrics, and the results show the interest of this approach.In the third part, the problem is addressed from a more theoretical point of view. Indeed, a system's degradation behavior is often correlated with internal and external covariates which are usually difficult to access owing to expensive measurement cost. Therefore, we first developed a prognostic approach with online inspections on the degradation covariate at a different level, and then we propose an approach for RUL prognosis based on an ensemble of models using different sources at different levels. The RUL predictions of both models are dynamically aggregated on the basis of prognostic performance evaluated on a set of historical data. Consequently, the prediction accuracy is improved by overcoming both models' drawbacks and leveraging their strengths. In the last part, we extend the problem to multi-level prognostics and explore new possibilities, which open new aspects for future research on PEMFC lifetime prognosis and management.
