Ruhl, R C

A fuel cell is described for oxidizing a fuel to produce electrical energy comprising: a plate-like, gas-impervious separator including a first internal hole passing through the first separator for receiving a gaseous fuel; a plate-like oxide powder cathode in contact with the first separator and including a second internal hole passing through the cathode for receiving a gaseous fuel, the second hole being in at least partial registration with the first hole; a plate-like, gas-impervious solid electrolyte in contact with the cathode and including a third internal hole passing through the electrolyte, the third hole being in at least partial registration with the first hole; a substantially gas-impervious tubular gasket disposed within the second hole and sealingly contacting the electrolyte to protect the cathode from fuel within the first hole; and a plate-like powder anode in contact with the solid electrolyte and including a fourth internal hole passing through the anode, the fourth hole being in at least partial registration with the first hole.
