Development and validation of a computational model for a proton exchange membrane fuel cell
… and release within the polymer portion of the catalyst layers, and liquid water production and transport. Both two-dimensional and three-dimensional geometries are modeled. For a given geometry, the governing differential equations are solved over a single computational domain. For the …

Catalyst Layer Design in Polymer Membrane Fuel Cells
… membrane fuel cells is the use of platinum as a catalyst. One way to overcome this obstacle is to replace platinum with non-platinum group metal (non-PGM) catalysts, particularly for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). The most realistic method of …

Design and characterization of catalysts and electrodes for electrochemical energy conversion applications
… electrochemical characterization, variation in catalyst layer morphology can be directly correlated to electrode performance. Depositing catalyst layers via a fully-automated air-brushing method led to a 56% improvement in fuel cell performance and a significant reduction in …
