Fuel cell vehicle
First Claim
1. A fuel cell vehicle having a vehicle body and a polymer electrolyte fuel cell mounted in said vehicle body, said fuel cell including a stack (12) formed by stacking a plurality of unit power generation cells, a stack container case containing said stack, and a condenser provided in said stack container case wherein in said polymer electrolyte fuel cell, each of said unit power generation cells includes an electrolyte electrode assembly and a first separator and a second separator sandwiching said electrolyte electrode assembly, said electrolyte electrode assembly including an anode electrodes, a cathode electrode, and a solid polymer electrolyte interposed between said anode electrode and said cathode electrode;
- said stack is immersed in an electrically insulating liquid coolant inside said stack container case to cool said stack;
said stack container case is provided under a passenger compartment of said vehicle body; and
an air supplied from an air inlet of said vehicle body contacts said condenser to condense the liquid coolant vaporized at said stack container case when cooling said stack.

Abstract
A stack of a polymer electrolyte fuel cell is immersed in a stack container case, in a liquid coolant such as an organic solvent, and the stack is operated in this state. The stack whose temperature has risen by heat energy produced by the operation is cooled by the liquid coolant. The liquid coolant which has cooled the stack vaporizes, and is condensed by a condenser. Then, the liquid coolant returns to the stack container. The condenser is cooled when the outside air is supplied into supply louvers, and contacts the condenser. The outside air is efficiently discharged by exhaust fans through exhaust louvers.
