The Journal of Physical Chemistry C. 124:24052-24065
Proton exchange membrane fuel cells (PEMFCs), fed with oxygen from ambient air and hydrogen, spontaneously produce power. However, key materials, gas diffusion layers, catalysts, ionomers, and membranes, are sensitive to a multitude of other species

Proton exchange membrane fuel cell (PEMFC) water management and current density are highly sensitive to the gas diffusion media (GDM) used at both the anode and the cathode. As the gas and mass transport requirements vary at each of these electrodes,

Low system complexity and high hydrogen utilization are important attributes for effective proton exchange membrane fuel cells (PEMFCs). Operating a PEMFC with a dead-ended anode (DEA) mode configuration is a simple and effective way to solve these t

The cost and durability of proton exchange membrane fuel cells (PEMFCs) still limit their adoption as sustainable power systems [1]. Operation at high current densities, which decreases the inventory of costly materials [2], is still considered an op
