The hydrogen supply system (HSS) is an important part to ensure the efficient and reliable
operation of fuel cells. As one of the key equipment of hydrogen supply system, the …

Through a tight collaboration between chemical engineers, polymer scientists, and
electrochemists, we address the degradation mechanisms of membrane electrode …

Nitrogen and water accumulations in fuel cells with dead-ended anode can cause severe
cell performance decline and fluctuations. In this work, both overall and local effects of fuel …

The dead-ended anode (DEA) configuration can simplify proton exchange membrane fuel
cell (PEMFC) systems and reduce system cost. However, the DEA configuration can also …

Polymer electrolyte membrane fuel cells have durability limitations associated with the
startup and shutdown of the fuel cell, which is critical for real-world vehicle …

The ionic resistance of a PEM fuel cell catalyst layer, as well as the double layer capacity
and the high frequency resistance are estimated from the impedance spectra of H 2/N 2 …

To improve the lifetime of proton-exchange membrane (PEM) fuel cells, it is necessary to
provide a better understanding of the degradation mechanisms of the perfluorosulfonic acid …

Proton exchange membrane (PEM) fuel cells operate with dead-ended anode in order to
reduce system cost and complexity when compared with hydrogen re-circulation systems. In …

Operating a proton exchange membrane (PEM) fuel cell with a dead-ended anode may lead
to local fuel starvation due to the excessive accumulation of liquid water and possibly …

This paper presents a study of the carbon support corrosion and mitigation strategies
through the use of a pseudo-3D model. This model consists in coupling a 2D model along …
