<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell stack, which is compact but has a large reaction area, smoothly supplying gas. <P>SOLUTION: A solid polymer fuel cell stack is provided with a plurality of coolant channels formed in each part of a separator, arranged around the channel for fuel gas and a channel for oxidizing gas and making coolant flow in a direction perpendicular to a surface of the separator. The channel for oxidizing gas is provided with an oxidizing gas inlet on one end and an oxidizing gas outlet on the other end. The coolant channels are provided with coolant inlets on one end and coolant outlets on the other end. The coolant inlets are installed in places adjacent to the oxidizing gas inlets, the coolant inlets and the oxidizing gas inlets are oriented in the same direction, the coolant outlets are adjacent to the oxidizing gas outlets and the coolant outlets and the oxidizing gas outlets are oriented in the same direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
