Fuel cell system and fuel cell automobile power system

Abstract

The invention relates to a fuel cell system and a fuel cell automobile power system. The fuel cell system comprises a hydrogen fuel cell and a cooling system, wherein the cooling system is mainly composed of a circulating pump, a thermoelectric device, an electric three-way valve, a mechanical three-way valve, a cooling medium filtering device, a cooling medium deionizing device and a cooling medium circulating pipeline. The fuel cell automobile power system is composed of a hydrogen fuel cell system, a DC / DC converter 1 for carrying out voltage matching on electric energy output by a hydrogenfuel cell, a power cell, a DC / DC converter 2 for carrying out voltage matching on electric energy output by the thermoelectric device contained in the hydrogen fuel cell system, a motor controller and a driving motor. The thermoelectric principle is utilized to replace a method of using a cooling water tank and a cooling fan to dissipate heat in a classic automobile fuel cell system, so that theproblem of energy waste caused by waste heat emission and auxiliary device energy consumption during normal operation of the hydrogen fuel cell can be effectively solved, and the automobile provided with the power system has longer endurance mileage and better high-temperature environment adaptability.

Description

technical field [0001] The invention relates to a fuel cell system and a fuel cell vehicle power system based thereon, belonging to the field of vehicle energy technology. Background technique [0002] With the increasingly prominent environmental and energy issues, new energy vehicles have become a research hotspot for major automobile manufacturers and R&D institutions in the world.
