Abstract

A fuel cell which converts chemical energy from a fuel/oxidant gas mixture to electricity for power usage or gas-sensing applications is disclosed. The fuel cell has a solid electrolyte wall with electrodes on each side. Each side of the wall is surrounded by a partition which forms a first and second chamber whereon the fuel/oxidant gas mixture is allowed to diffuse. Means are provided to initiate a voltage drop between the electrodes which initiates the chemical reaction. Electricity is collected from the electrodes. In an alternate design the fuel cell has a first and second electrolyte wall with electrodes on each side of the walls. A partition wall separates the first and second walls thereby forming a first chamber with the first wall and the partition wall and a second chamber with the partition wall and the second wall. Gas-flow limiting means exist between the fuel/oxidant gas mixture and the first chamber and the first chamber and the second chamber. The chemical reaction starts spontaneously and electricity is collected and stored from each set of electrodes.
