Abstract

The invention relates to a fuel cell emergency power generation system based on a solid hydrogen storage technology. The fuel cell emergency power generation system comprises a fuel cell, a first hydrogen storage device, a second hydrogen storage device and a hydrogen supply channel, wherein the fuel cell can supply power to the system and other external equipment; the first hydrogen storage device can release hydrogen at a relatively low temperature, and generally, the environment temperature is minus 15 DEG C; the second hydrogen storage device can release hydrogen at normal temperature, and generally, the environment temperature is 25 DEG C; and the hydrogen supply channel can convey hydrogen released by the first hydrogen storage device and the second hydrogen storage device to the fuel cell. By switching the hydrogen supply modes of the first hydrogen storage device and the second hydrogen storage device, hydrogen can be supplied to the fuel cell under the conditions of lower temperature and normal temperature, so that the fuel cell can respond to the power demand at any time at different temperatures and immediately enter a working state, and the problems that a certain time needs to be consumed in the heating process of an existing solid hydrogen storage device, and the device is difficult to guarantee hydrogen supply to the fuel cell rapidly are solved.

Description

technical field [0001] The invention relates to the field of fuel cell technology, in particular to a fuel cell emergency power generation system based on solid hydrogen storage technology. Background technique [0002] Proton exchange membrane fuel cells using hydrogen have the advantages of high energy conversion efficiency, clean and pollution-free, and have entered commercial use. Hydrogen supply is a very important link in fuel cell operation. The solid-state hydrogen storage device based on hydrogen storage alloy has the characteristics of safety, high efficiency and high purity of hydrogen as a hydrogen source for fuel cells, and has great potential for application in the field of fuel cell emergency power generation systems. [0003] The hydrogen storage alloy releases heat during the hydrogen absorption process, and the hydrogen release process needs to absorb heat. The temperature has a significant impact on the hydrogen absorption and desorption performance of th...
