Abstract
A fluid resistance section outside a fuel cell can regulate the reactant flow against the pressure changes in the reaction zones of the electrodes, reducing the fluctuations in reactant flows to the fuel cell electrodes due to dynamic fluctuations in fluid pressure at the fuel cell electrode because of the release of gaseous products. The outside fluidic resistor can have resistance much higher than the resistance of the flow through the electrodes, thus effectively determining the amount of the reactant flow to the electrodes, independent of the electrode areas.
