摘要： A self-humidifying polymer electrolyte membrane (PEM) fuel cell assembly has an ion-exchange membrane interposed between hydrogen and oxygen diffusion layers to form a membrane electrode assembly (MEA). The MEA is in turn interposed between a pair of current collector plates having flow field channels for flowing the reactants adjacent the respective diffusion layers to produce corresponding anodic and cathodic electrochemical reactions. Various embodiments of the assembly incorporate one or more of the following features: interdigitated flow field channels, countercurrent reactant flows, opposing channel alignment, and uncatalyzed membrane hydration enhancement zones.
