Heat exchange humidifying device for fuel cell

Abstract

The invention relates to the technical field of fuel cells, in particular to a heat exchange humidifying device for a fuel cell, which comprises an intercooler inlet cavity, an intercooler main body is arranged on the top surface of the intercooler inlet cavity, a humidifier main body is arranged on the surface of the intercooler main body, a gas mixing cavity is arranged on the surface of the humidifier main body, and an adapter is arranged on the surface of the gas mixing cavity. The heat exchange humidifying device has the beneficial effects that the heat exchange humidifying device for the fuel cell is small in size and high in integration level; and, through simulation design, the welding angle of the baffle is changed, under the condition that the length of an inlet pipeline of the intercooler is not increased, the uniformity of gas distribution is guaranteed, the intercooler, the humidifier and a throttle valve (or a tee joint) can be integrated at the same time, and the use of pipelines is reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a heat exchange and humidification device for fuel cells. Background technique [0002] Fuel cell system refers to the power generation system with fuel cell as the core, fuel supply and circulation system, oxidant supply system, water / heat management system, control system, etc.; a single fuel cell stack cannot be used for power generation, it must be The fuel cell power generation system is composed of fuel supply and circulation system, oxidant supply system, water / heat management system, and control system to output power externally. [0003] In the prior art, the fuel cell system needs to cool and humidify the air during the reaction process. According to the prior art, the intercooler is used to solve the cooling problem, and the humidifier is used to solve the humidification problem.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the fuel cell system needs to cool and humidify the air during the reaction process. According to the prior art, the intercooler is used to solve the cooling problem, and the humidifier is used to solve the humidification problem. To connect, the volume is large and there are many pipelines, which is not conducive to system integration

Even if there is a partial integrated design that integrates the two together, the length of the inlet pipe of the intercooler and the variable diameter are increased to meet the usage requirements, which increases the volume of the components and wastes the integration space
