Water balance has been proven to be critical not only for the performance but also for the
durability of proton exchange membrane fuel cells (PEMFCs). This paper reviews …

Over the past few years, the importance of water management to the successful operation of
polymer electrolyte membrane (PEM) fuel cells has stimulated an extensive research focus …

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 …

Nanocoatings consisting of ammonium polyphosphate (APP), sodium montmorillonite
