EP--55011 A A high temperature solid oxide electrolyte fuel cell converts chemical energy directly into D.C. electrical energy when operating at temperatures in excess of 700 deg.C. The high temperature renders the electrolyte sufficiently conductive to achieve a low level of ohmic loss. - The device constitutes a gas-tight housing surrounding multiple chambers which include a generating chamber and a combustion product, or preheating, chamber which extends between the porous barrier and a tube support structure. The oxidant inlet chamber extends between the support structure and the end wall of the housing. - Electrochemical reaction takes place whilst the oxidant traverses the insides of the fuel cells. Depleted oxidant, discharged from the open ends, and hot depleted fuel diffusing through a porous barrier, are directly reacted in the combustion product chamber to preheat incoming reactants and to facilitate combustion of the remaining fuel.
