This paper presents a systematic fault analysis and diagnosis method of PEM fuel cell control system using model-based approach. With approach, it is possible to analyze the causal relationship effect probable faults in system, diagnose them under assumption that model process are similar. In this work, approach was adopted for diagnosis, its methods suggested. A mathematically modelled, analyz...

<span lang="EN-US">Among the different clean energy conversion devices, fuel cells systems are largely employed due to their high-power densities and efficiencies. Several models available in literature characterize functioning, both for stationary dynamic behaviors. Vehicular application of a cell requires model that is accurate enough, simple enough quick computations real-time reportin...

Polymer Electrolyte Membrane (PEM) fuel cells incorporating microchannels (D<500 μm) can benefit from improved fuel delivery and convective cooling. However, this requires a better understanding of twophase microchannel transport phenomena, particularly liquid-gas interactions and liquid clogging in cathode air-delivery channels. This paper develops optical fluorescence imaging of water films i...

In this work, we focus on robustness analysis of an integrated fuel cell and fuel reforming (FCFR) system, which relies on a feedback controller to mitigate hydrogen starvation and temperature overshoot during load transitions. The fuel reformer is used to process natural gas into a hydrogen rich flow to be utilized in a proton exchange membrane fuel cell (PEM-FC). The feedback controller uses ...
