COOLING SYSTEM FOR HYDROGEN ENERGY FUEL CELL OF TRAM

摘要

A cooling system of a hydrogen-energy tram fuel cell, comprising: a hydrogen fuel cell (1), a circulation device, a cooling device and an electric heating tube (12); the hydrogen fuel cell (1), the circulation device and the cooling device are sequentially connected by pipelines, and form a cooling circulation loop; one end of the electric heating tube (12) is connected with the circulation device by means of the pipelines, while the other end thereof is in communication with the hydrogen fuel cell (1) by means of the pipelines, thus forming a heating circulation loop. The cooling system can precisely and relatively stably control the temperature of a cooling liquid when entering the hydrogen fuel cell (1) to be within an optimal reaction temperature range, such that the hydrogen fuel cell (1) is in a suitable reaction temperature environment, thus improving the reaction efficiency of the hydrogen fuel cell (1); the cooling system is structurally simple, notably effective and energy-saving.
