Mixed reactant fuel cells with flow through porous electrodes

摘要

A fuel cell or battery for providing useful electrical power by electrochemical means, comprises: at least one cell; at least one anode and at leas one cathode within said cell, and ion-conducting electrolyte means for transporting ions between the electrodes; and is characterised in that: said electrodes are porous and in that means are provided for causing hydrodynamic flow of a mixture of at least fuel and oxidant through the body of said electrodes.
