摘要： PURPOSE:To enhance the output density of a fuel cell without lowering mechanical strength and to enhance the productivity and serviceability of the fuel cell by arranging the coplanar unit cells of a unit cell collective set so that adjacent cells have different polarities. CONSTITUTION:A fuel cell comprises a number of unit cell collective sets 9 stacked on stop another via gas passage members 11 each having a manifold through hole 14, each of the cell sets 9 having a plurality of flat units cells 1 arranged coplanar with one another using a cell frame portion 6 having a manifold through hole 14. The coplanar unit cells 1 of each set 9 are arranged so that adjacent cells have different polarities. An effective electrode reaction area can then be increased per stage of laminate without causing the deterioration of mechanical strength and so output density is increased and anode and cathode terminals can be taken out from the same direction, whereby the productivity and serviceability of the fuel cell are remarkably enhanced.

Therein the operating temp. can be made below 700 deg.C by using an oxygen ion electroconductive solid electrolyte of Bi2O3-Y2O3 type, and also deterioration of the battery members by heat be suppressed. Further it is made practicable to use an easy-to-process metal as battery members, and the reliability and operating easiness are enhanced as the whole fuel battery.
