摘要： A flow battery includes a liquid electrolyte having an electrochemically active specie. A flow field plate includes a first flow field channel and a second flow field channel that is separated from the first flow field channel by a rib. There is a flow path for the liquid electrolyte to flow over the rib between the channels. An electrode is arranged adjacent the flow field plate such that the liquid electrolyte that flows over the rib must flow through the electrode. The electrode includes a carbon paper that is catalytically active with regard to liquid electrolyte. The carbon paper defines a compressive strain of less than 20% at a compressive stress of 0.8 MPa and an uncompressed porosity in the range 60-85%.

摘要： An example method of controlling fluid distribution within a fuel cell includes adjusting a flow of a reactant moving within a fuel cell to increase water within a portion of the fuel cell. Another example method of controlling fluid distribution within a fuel cell includes adjusting a flow of fuel entering a fuel cell, a velocity of air entering the fuel cell, or both, so that a first amount of water exiting the fuel cell in a fuel stream is about the same as a second amount of water exiting the fuel cell in an airstream.
