Abstract:
1. An electrochemical cell for the separation of hydrogen and oxygen from water comprising: a. a first plenum containing a fuel inlet for filling said first plenum with fuel; b. a second plenum containing oxidant; c. a porous substrate communicating with said first plenum, and said second plenum further comprising a top, a bottom, a first side and a second side; d. an undulating channel formed in said porous substrate having a first channel wall and a second channel wall; e. a support member disposed between said first channel wall and said second channel wall; f. an anode formed from a first catalyst layer disposed on said first channel wall; g. a cathode formed from a second catalyst layer disposed on said second channel wall; h. electrolyte disposed in said undulating channel contacting the anode and the cathode forming a barrier preventing transfer of fuel to the cathode and preventing transfer of oxidant to the anode; i. a first coating disposed on at least a portion of said porous substrate to prevent fuel from entering said porous substrate; j. a second coating disposed on at least a portion of said porous substrate for preventing oxidant from entering said porous substrate; k. wherein said first plenum and said second plenum are separated by the porous substrate and the electrolyte, such that fuel and oxidant are blocked from said anode and said cathode by the electrolyte; l. a sealant barrier disposed on said porous substrate between said first plenum and said second plenum opposite said anode and said cathode; and m. a negative electrical connection disposed on said second side of said porous substrate for flowing current from said electrochemical cell to an outside source and a positive electrical connection disposed on said first side of said porous substrate for flowing current from said outside source to said porous substrate.
