Cooling system for a hydrogen fuel cell of a tram

摘要

A cooling system for a hydrogen fuel cell of a tram includes a hydrogen fuel cell (1), a circulation device, a cooling device and an electric heating tube (12), wherein the hydrogen fuel cell (1), the circulation device and the cooling device are connected in series by means of pipelines and form a cooling circulation loop; and wherein the one end of the electric heating pipe (12) is connected to the circulation means through a pipe and the other end is connected to the hydrogen fuel cell (1) through a pipe to form a heating circulation loop. In the present invention, the temperature of the coolant as it enters the hydrogen fuel cell (1) can be accurately and stably controlled within an optimum reaction temperature range, so that the hydrogen fuel cell (1) is in an appropriate reaction temperature condition to maintain the reaction efficiency Hydrogen fuel cell (1) to improve. Moreover, the present invention has a simple structure and a pronounced effect and can save energy.
