Abstract:
1. A solid oxide fuel cell, comprising: a plurality of unit cells each including a support body block, the support body block including a first surface, a second surface parallel to the first surface, a plurality of first channels extending in a first direction in a parallel relationship with the first surface and serving as flow paths through which an air flows and a plurality of second channels existing between the first channels and serving as flow paths through which fuel flows, the first channels having first-surface-side open ends and second-surface-side open ends, the second channels having first-surface-side open ends and second-surface-side open ends, each of the unit cells further including air electrodes (cathodes) formed on inner surfaces of the first channels, fuel electrodes (anodes) formed on inner surfaces of the second channels, a first electricity collecting layer formed on the first surface and electrically connected to the air electrodes and a second electricity collecting layer formed on the second surface and electrically connected to the fuel electrodes; a first side plate and a second side plate respectively attached to opposite lateral surfaces of the unit cells and configured to close lateral ends of the first channels and the second channels; a first electricity collector electrically connected to the first electricity collecting layer and arranged to partially close the first-surface-side open ends of the first channels of the unit cells; and a second electricity collector electrically connected to the second electricity collecting layer and arranged to partially close the second-surface-side open ends of the second channels of the unit cells, wherein the unit cells are stacked one above another such that the first channels of the unit cells adjoining each other are connected to one another to form the flow paths through which the air flow and such that the second channels of the unit cells adjoining each other are connected to one another to form the flow paths through which the fuel flow, the first surfaces of the unit cells adjoining each other arranged to face each other with the first electricity collector interposed therebetween, the second surfaces of the unit cells adjoining each other arranged to face each other with the second electricity collector interposed therebetween.
