Abstract
A fuel cell includes a catalyst layer, a corrugated plate forming a plurality of channels that define a flow field in fluid communication with the catalyst layer, and a coating on at least one of the channels. The plate and coating are configured such that, if a gas flows through the channels, an obstruction blocking the at least one of the channels causes a pressure gradient between the channels that drives convection of the gas through the coating and around the obstruction.
