Abstract
A fuel cell stack comprises a power-generating cell and a cooling cell which are stacked, an insulating means for electrically insulating the cooling medium supplied into the cooling cell from the power-generating cell, and a conducting means for electrically connecting the power-generating cells arranged with the cooling cell interposed therebetween to one another. Accordingly, the earth fault and the liquid junction, which would be otherwise caused by cooling medium, is reliably avoided with a simple structure, making it possible to maintain desired power generation performance.
