A comprehensive test system for proton exchange membrane fuel cells (PEMFCs) is designed and developed monitoring controlling the inlet outlet parameters safety issues of cells. The data acquisition output instruction rely on connection between PLC (programmable logic controller) OPC (object linking embedding process control). Based Siemens S7-200 series PID (proportion integration differentiat...

We have successfully fabricated hydrogen–air micro proton exchange membrane fuel cells (PEMFC) on silicon and polydimethylsiloxane (PDMS) base substrates. A complete fuel cell system was fabricated consisting of a PDMS substrate with micro flow channels upon which the membrane electrode assembly was vertically stacked. The PDMS microreactor was fabricated by soft lithography techniques. The mem...

In this paper, a three-dimensional, single-phase proton-exchange membrane fuel cell (PEMFC) is studied numerically. Finite volume method was used for solving the governing equations and, consequently, the numerical results were validated by comparing them with experimental data, which showed good agreement. The main objective of this work is to investigate the effect of a novel gas channel shap...
