Abstract Proton-exchange membrane (PEM) cells fuel are being used as highly efficient and zero-emission power units to produce electricity from a renewable source. The purpose of the current study is present design simple PEM type cell model that can be in an educational environment. has illustrated possibility through product specification (PDS) process. Three different designs were studied ra...

Today the world is full of time-dependent phenomena in all fields: physics, chemistry, mechanics and many others. Time acts on performance any system whatever its nature is. When a operates over time, aging becomes real concern. Regarding fuel cells, several degradation can occur short or long term. Short-term are generally referred to as reversible degradations, these degradations order micros...

This paper deals with the performance analysis of a proton exchange membrane fuel cell in automotive applications and especially for start/stop phases. Start-Stop cycles are one main sources degradation systems, embedded applications, among other dynamic conditions as idling, load cycling or high power. In this study, polarization curves electrochemical impedance spectra used to analyze mechani...
