Fuel cell power system and automobile power system thereof

Abstract

The invention provides a fuel cell power system. The system comprises an air supply module, a hydrogen supply module and a fuel pile module; an air inlet side and an exhaust side are formed on the fuel pile module; the air inlet side is communicated with the air supply module and the hydrogen supply module; a cooling element is arranged at the exhaust side; the cooling element can control the velocity of the air entering the fuel pile module from the air supply module; the air supply module comprises an air inlet pipeline, and the air inlet pipeline is communicated with the fuel pile module. The cooling element can control the velocity of the air entering the fuel pile module from the air supply module; on the one hand, the air flow required by the fuel pile module reaction can be satisfied, on the other hand, the cooling effect on the fuel pile module can be achieved. The air is input into the fuel pile module by adopting the air inlet pipeline so as to play the effect of preventing water and dust. The fuel cell power system provided by the invention is high in air inlet quality, convenient for cooling inlet air, and good in effect, and has great practical value. The invention further provides an automobile power system.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell power system. Background technique [0002] Fuel power system and pure electric power system are the main power systems of automobiles and other vehicles at present. However, the traditional fuel power system and pure electric power system have many deficiencies. The operation noise of the traditional fuel power system is large, which constitutes a certain amount of noise pollution, and the traditional fuel power system emits carbon dioxide, monoxide and other gases due to incomplete combustion of fuel, causing environmental pollution. Pure electric power systems have certain disadvantages in terms of battery life and battery usage, specifically: pure electric power systems mostly use lithium-based batteries as the power source, but at present, lithium-based batteries have limited energy density, resulting in very limited discharge endurance. The charging time of ...

AI Technical Summary

Problems solved by technology

However, the current fuel cell power system has high intake air pollution and noise, and the air cooling effect of the exhaust fan alone is poor.

Lead to poor performance and shortened service life of fuel cell power system
