Abstract

The invention relates to a gas heating device, particularly to a hydrogen heating device, namely a device for heating hydrogen, wherein the device is used in a proton exchange membrane hydrogen fuel cell system. When a fuel cell vehicle runs in a low-temperature environment, low-temperature hydrogen is continuously input into a fuel cell stack, so that the temperature of the stack near a hydrogen inlet is reduced, normal power generation of the stack is not facilitated, and the stack generates stress strain due to temperature change so as to easily damage the stack structure. According to the invention, the problem is solved by heating hydrogen by using fuel cell cooling liquid to bring away heat generated by a fuel cell; and the device comprises a heating box, a hydrogen input pipeline, a hydrogen output pipeline, a hydrogen reflux pipeline, a heat exchange device, a hydrogen heating flow control valve, a cold-state hydrogen flow control valve, an input temperature detector, an output temperature detector, a hydrogen flow mixing device and the like.

Description

technical field [0001] The invention relates to a gas heating device, in particular to a hydrogen heating device, that is, a device for heating and raising the temperature of hydrogen, which is used in a proton exchange membrane hydrogen fuel cell system. Background technique [0002] Proton exchange membrane hydrogen fuel cells are widely used in the fields of stationary power generation, portable power generation, and transportation, especially in fuel cell electric vehicles, where the fuel cell engine is the core component. The power generation temperature of the proton exchange membrane hydrogen fuel cell stack is tens to one hundred degrees Celsius. For example, the power generation temperature of the widely used low-temperature proton exchange membrane hydrogen fuel cell is between 60 degrees Celsius and 80 degrees Celsius. If the fuel cell stack exceeds In this temperature range, the fuel cell cannot generate electricity normally, or even be damaged. When a fuel cell...
