In this comprehensive review, recent progress and developments on perfluorinated sulfonic-
acid (PFSA) membranes have been summarized on many key topics. Although quite well …

Polymer-electrolyte fuel cells are a promising energy-conversion technology. Over the last
several decades significant progress has been made in increasing their performance and …

Abstract Electrochemical CO 2 reduction (CO 2 R) is an attractive option for storing
renewable electricity and for the sustainable production of valuable chemicals and fuels. In …

The effect of cathode platinum loading on oxygen transport resistance in a fuel cell electrode
was determined by measuring limiting current in fuel cells over a wide range of platinum …

The quantification procedure of oxygen-transport resistances for different fuel-cell layers and
phenomena is described. The total transport resistance is obtained from limiting-current …

Abstract Proton Exchange Membrane Fuel Cells (PEMFC) are energy efficient and
environmentally friendly alternatives to conventional energy conversion systems in many yet …

Hydrogen has higher specific energy than conventional fuels but compared per unit volume
under normal conditions, its energy density is lower. This difference is compensated with …

Thin films of ion‐conducting polymers are an important area of study due to their function in
many electrochemical devices and as analogues for interfacial phenomena that occur in …

In this article, a two-dimensional, multiphase, transient model is introduced and used to
explore the impact of catalyst-layer thickness on performance. In particular, the tradeoffs …

Theoretical models used to describe the proton-conductive membrane in polymer electrolyte
membrane fuel cells (PEMFCs) are reviewed, within the specific context of practical …
