Abstract

The invention discloses a hydrogen storage material reaction chamber and a fuel cell power generation device. The fuel cell power generation device comprises a water tank, a water pump and a fuel cellgroup. The fuel cell power generation device has the following characteristics: the outlet of the water tank is connected with the inlet of the water pump through a pipeline; the outlet of the waterpump is connected with a first connecting interface of the reaction chamber through a pipeline; and the second connecting interface of the reaction chamber is connected with the fuel cell group through a pipeline. According to the invention, the hydrogen is produced by the hydrolysis of vapor and magnesium hydride, and the reaction heat is produced to provide the pyrolysis high temperature environment for the pyrolysis of the hydrogen storage material, so that the hydrogen storage material can be pyrolyzed in the high temperature environment to release the hydrogen, and the generated hydrogenis supplied to the fuel cell for power generation. According to the invention, no extra heating equipment is needed, and the disadvantages of extra weight, extra volume and energy consumption are eliminated; meanwhile, the chamber wall temperature of the reaction chamber can be further reduced by means of the heat absorption by hydrogen release characteristic of the pyrolysis of the hydrogen storage material, therefore, the thickness of the high temperature protective cover can be reduced, and the volume and weight of the product can be reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a hydrogen storage material reaction chamber and a fuel cell power generation device thereof. Background technique [0002] Hydrogen can be converted into electricity by fuel cells. There are two sources of hydrogen, one is stored in a container, which can be a high-pressure liquid hydrogen storage method; the other is stored in a material, called a hydrogen storage material. The high-pressure hydrogen storage method has the risk of high-pressure leakage, and the liquid hydrogen storage method has the problem of boiling liquid hydrogen when the temperature rises. The hydrogen storage method of hydrogen storage materials is recognized as the safest hydrogen storage method. Hydrogen is extracted from the hydrogen storage material and supplied to the fuel cell to generate electricity. [0003] Magnesium hydride (MgH 2 ) is a known hydrogen storage material, which can react wit...
