Ultralow Loading and High-Performing Pt Catalyst for a Polymer Electrolyte Membrane Fuel Cell Anode Achieved by Atomic Layer Deposition

ACS Catalysis, 2019
Decreasing Pt loading in the anode layer below ∼0.025 mg·cm–2 is found to reduce the hydrogen oxidation reaction rate during polymer electrolyte membrane fuel cells (PEMFCs) normal operation, when using conventional Pt/C catalysts and electrode coating ...

Fatigue‐Resistant Polymer Electrolyte Membranes for Fuel Cells

Advanced Materials, 2023
AbstractIn a hydrogen fuel cell, an electrolyte membrane conducts protons, but blocks electrons, hydrogen molecules, and oxygen molecules. The fuel cell often runs unsteadily, resulting in fluctuating water production, causing the membrane to swell and contract. The cyclic deformation can cause fatigue crack growth.

Modeling of Polymer Electrolyte Membrane Fuel Cells

2023
This chapter outlines analytical and numerical methods for modeling proton exchange membrane fuel cells. To provide the fundamentals of fuel cell simulation, a monodimensional analytical (steady-state isothermal) model for reconstructing the cell polarization curve is presented and then applied to a case of practical interest. The monodimensional model
