Abstract

The invention relates to a gas heating device, in particular to a hydrogen electric heating device, namely a device for heating hydrogen in an electric heating mode, and the hydrogen electric heating device is used in a proton exchange membrane hydrogen fuel cell system. When a fuel cell automobile runs in a low-temperature environment, low-temperature hydrogen is continuously input into a fuel cell stack, so that the temperature of a galvanic pile near a hydrogen inlet is reduced, normal power generation of the galvanic pile is not facilitated, meanwhile, the galvanic pile generates stress strain due to temperature change, and the structure of the galvanic pile is easily damaged. According to the invention, hydrogen is heated in the electric heating manner, so that the problem is solved. The device includes a heating box, a hydrogen input pipeline, a hydrogen output pipeline, a hydrogen return pipeline, a heat exchange device, an electric heater, 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 electric heating device, that is, a device for heating hydrogen by electric heating, 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 e...
