NOVELTY - A fuel cell comprises first and second flow field plates; an electrolyte between the flow field plates; catalytic electrodes for promoting the dissociation of a fuel at a first face of the electrolyte and the formation of water at a second face of the electrolyte; and a delivery system for delivering a gaseous fuel through the first plate to the first face of the electrolyte, and having an array of nanotubes.    USE - As a fuel cell.    ADVANTAGE - The inventive cell provides for the delivery of current at voltages consistent with the practical application of the fuel cells, which is not true of conventional proton-exchange membrane fuel cells. It optimizes the confining of the reactant gases to the desired areas of flow in a membrane-minimizing configuration. It increases fuel cell performance with high current densities.
