Title: Fuel cell water management via reduced anode reactant pressure

Abstract

A method is provided for operation of a fuel cell with improved water management by maintaining reduced anode pressure relative to cathode pressure, relative to atmospheric pressure, or both. Typically, the fuel cell comprises a membrane electrode assembly comprising nanostructured thin film cathode catalyst.
