ABSTRACT:
The invention is an electrochemical cell for the separation of hydrogen and oxygen from water made of a fuel plenum with a fuel inlet, a oxidant plenum, a porous substrate, an undulating channel with walls, a support member between the walls, an anode and a cathode in the walls, an electrolyte contacting the anode and the cathode forming a barrier preventing transfer of fuel and oxidant to the cathode or to the anode, a two separate coatings on the porous substrate to prevent fuel or oxidant from entering the porous substrate, a sealant barrier to divide the two plenums, and a negative electrical and a positive electrical connection on the side of the porous substrate for flowing current from an outside source to the porous substrate.
