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...

The study focuses on the challenges of implementing fuel cell technologies and materials to achieve efficient use green hydrogen zero CO2 emissions. It is shown that only identifying optimal parameters for each component technology testing system will help planned output-specific power. thorough structure optimization membrane-electrode complex in actual operating conditions accelerate implemen...

Anion exchange membrane (AEM) electrolysis aims to combine the benefits of alkaline electrolysis, such as stability cheap catalyst and advantages proton-exchange systems, like ability operate at differential pressure, fast dynamic response, low energy losses, higher current density. However, today, AEM is limited by AEMs exhibiting insufficient ionic conductivity well lower activity stability. ...

Proton exchange membrane fuel cells (PEMFCs) have been recognized as a promising power generation source for wide range of automotive, stationary, and portable electronic applications. However, the durability PEMFCs remains one key barriers to their commercialization. The electrode assembly (MEA) central part PEMFC, which consists proton with catalyst layer (CL) gas diffusion (GDL) on each side...

Although proton-exchange membrane fuel cells (PEMFC) are considered as a safe and clean energy technology, aging phenomena of the membrane-electrode assembly (MEA), more particularly membrane, still restrict PEMFC lifetime. In this paper, ex-situ accelerated chemical degradation – via Fenton's reagents exposure reinforced Nafion™ XL is performed in order to investigate impact on structure prope...
