Abstract
A fuel cell comprising a pair of electrodes and an electrolyte body comprising an electrolyte-retainable material and an electrolyte retained in the electrolyte-retainable material, the electrolyte body being provided between the pair of electrodes, characterized by the electrolyte body being integrated with at least one of the pair of the electrodes. The fuel cell has a good sealing between the electrodes and the electrolyte body.
Claims14
A fuel cell comprising at least a pair of electrodes of electron conductive catalytic refractory material and at least an electrolyte body comprising an electrolyte-retainable porous, refractory, non-electron conductive, inorganic material and an electrolyte retained in the electrolyte-retainable porous material, the electrolyte body being provided between the pair of the electrodes, an oxidizing agent passage means for supplying an oxidizing agent to one of the electrodes, a fuel passage means for supplying a fuel gas to the other electrode, wherein an improvement comprises the electrolyte body being integrated with at least one of the pair of the electrodes through an intermediary provided between at least one of the pair of the electrodes and the electrolyte body, the intermediary being embedded in both the at least one of the electrodes and the electrolyte body.
