TL;DR: In this paper, the effects of hydrophobic polymer content within a carbon paper, used as the cathode gas diffusion layer (GDL), on power performance of a H2/air proton exchange membrane fuel cell (PEMFC) have been studied.

TL;DR: In this paper, a cyclic open circuit voltage accelerated stress test (AST) is designed to screen the simultaneous effect of chemical and mechanical membrane degradation in polymer electrolyte fuel cells.

TL;DR: In this paper, a liquid-feed direct methanol fuel cell (DMFC) was fabricated by using a novel method of modified Nafion solution and tape-casting, with unsupported Pt-Ru as an anode catalyst and carbon supported 40.% Pt as a cathode catalyst.

TL;DR: In this paper, the authors derived the Faradaic admittance of hydrogen absorption reaction (har) on metal membrane electrode by using an extension of Armstrong's kinetic approach and showed that in the case of the direct har without passing through the adsorbed phase (model B), the presence of adsorption capacitance from that based upon the model A is explained by the absence of the second semicircle, often found in the complexplane impedance spectra for hydrogen evolution reaction.

TL;DR: In this paper, a combined chemical and mechanical accelerated stress test (AST) was applied to simulate field operation and rapidly generate partially degraded CCM samples for tensile and expansion experiments under both room and fuel cell conditions.
