Proton exchange membrane (PEM) fuel cells are at the dawn of commercialization. Their
operation and design characteristics, hence their performance, are closely linked to the …

The urgent need for green energy to curb environmental pollution and solve the energy
crisis calls for the rapid development of clean power supplies. Besides proton exchange …

Enabling fuel cell operation at high current density is critical for developing competitive
alternative power system to replace internal combustion engine. However, liquid water …

Various flow field designs have been numerically investigated to evaluate the effect of
pattern and the cross-sectional dimensions of the channel on the performance of a large …

In this study, ex-situ experiments performed with a point injection device are conducted to
evaluate water distributions in gas diffusion layer (GDL) materials which serve as porous …

A three-dimensional, non-isothermal and two-phase flow model for proton exchange
membrane (PEM) fuel cells is developed. In the cathode catalyst layer, a spherical …

This study aims to evaluate the convective heat transfer enhancement of the proton
exchange membrane fuel cells (PEMFC) numerically. As the higher heat transfer surfaces …

The limiting current method is an effective in-situ diagnostic tool for studying oxygen
transport resistance in a PEM fuel cell. In this study, we present both experimental and …

The flow fields of bipolar plates are among the important factors that direct reaction, heat,
pressure, and mass transfer by distributing the reactants on the electrode surfaces, and thus …

This work uses neutron radiography to examine the through-plane liquid water distribution of
an operating polymer electrolyte membrane fuel cell (PEMFC) with a Sigracet SGL 25BC, a …
