Fuel cell device with a heat release means disposed on an automobile

Abstract

A fuel cell device that is designed to circulate cooling water with simplified and compact construction, without any need of a pump for circulating the cooling water, so as to reduce electric power loss. A fuel cell and a radiator are connected through a closed line via an inflow-side cooling pipe and an outflow-side cooling pipe and also the radiator is disposed under the wing of an air spoiler spaced above the fuel cell and open to outside air. With this arrangement, while the fuel cell generates electric power, the cooling water of decreased density flowing out of the fuel cell is allowed to rise through the outflow-side cooling pipe to feed it to the radiator and the cooling water of increased density that was cooled down by heat exchanging the cooling water and outside air is allowed to lower through the inflow-side cooling pipe to feed it to the fuel cell again.
