Claim:
1. A fuel cell stack formed by stacking an electrolyte electrode assembly and a separator in a stacking direction, the electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between the electrodes, rectangular end plates being provided at both ends of the fuel cell stack in the stacking direction, a pair of coolant supply passages and a pair of coolant discharge passages extending through two opposite long sides of the fuel cell stack in the stacking direction as passages for conducting a coolant therethrough; one of the end plates having a pair of short sides and a pair of long sides, and comprising: a pair of supply manifold sections communicating with the pair of the coolant supply passages and elongated along two sides of the end plate, each of the supply manifold sections including a portion which extends in a direction substantially parallel to the long sides of the end plate, the supply manifold sections being spaced apart from one another; and a supply coupling section for fluidly interconnecting the supply manifold sections and coupling the pair of supply manifold sections together, the coupling section extending in a direction substantially parallel to the short sides of the end plate; wherein a coolant supply pipe is coupled to one of the pair of supply manifold sections, said coolant supply pipe extending in a direction inclined at an angle which is in a range between 10 and 40 degrees, in relation to a line extending parallel to the long sides of the end plate.
