Abstract
A fuel cell cooling device includes a plurality of plate-like fuel cell units arranged in a vertical stack and having singly interspersed therein cooling plates. A main coolant pipe supplies coolant at a pressure above the saturation point thereof to the cooling plates through corresponding inlet cooling pipes. A throttle is provided in each inlet cooling pipe to produce a pressure drop such that coolant entering a cooling plate is at a pressure below the saturation point thereof.
