Abstract
A fuel cell includes a sheet-shaped solid electrolyte having opposite surfaces, and exhibiting ion conductivity, a plurality of fuel electrodes disposed adjacent to each other on one of the opposite surfaces of the solid electrolyte, to which fuel working as a negative electrode active material is supplied, a plurality of oxygen electrodes disposed adjacent to each other on the other one of the opposite surfaces of the solid electrolyte, to which oxygen working as a positive electrode active material is supplied, the fuel electrodes being electrically connected to the oxygen electrodes in series. The fuel cell is downsized and lightweighted, but can produce a high voltage output, because a plurality of fuel and oxygen electrodes are disposed on one cell. A plurality of the cells can laminated so as to face the same electrodes of the neighboring cells. The cell can further include an electricity collector, a cooling member, or a separator which is laminated on at least one of the fuel and oxygen electrodes.
