Abstract:
1. A dual chamber fuel cell that includes a gas-permeable catalyic combustor instead of a seal, comprising: an anode chamber for presenting fuel to an anode; a cathode chamber for presenting oxidizer to a cathode, wherein the anode chamber and the cathode chamber are coupled to form a continuous space within the fuel cell; a gas-permeable catalytic combustor in at least part of the continuous space to react at least some of the fuel with at least some of the oxidizer; wherein the gas-permeable catalytic combustor is located where normally a seal between the anode chamber and the cathode chamber is situated; and wherein the gas-permeable catalytic combustor is in physical contact with the anode, the cathode, or an electrolyte of the fuel cell.
