Hydrogen generator

Abstract

The invention relates to a hydrogen generator, specifically relates to a simple self-control pressure hydrogen generator, which comprises a fuel case(1) of a fuel inlet(2) and a catalytic reactor(6) fixedly arranged on the fuel case(1). An inner shell(3) in the fuel case separates the fuel case into two parts, namely, an inner chamber, i.e. a fuel reaction chamber(5) and an outer chamber, i.e. a fuel storing chamber(4); wherein, a gap is reserved between the bottom of the inner shell(3) and the bottom of the fuel case(1); moreover, the catalytic reactor(6) is positioned in the fuel reaction chamber(5) and can be removed, being convenient and quick to replace. The hydrogen generator provided by the invention has the advantages of simple structure, convenient operation, stable performance, self-control pressure and high safety, belonging to the hydrogen generator field for providing hydrogen to the fuel batteries.

Description

technical field [0001] The invention relates to a hydrogen generator, in particular to a simple self-control pressure hydrogen generator. Background technique [0002] With the increasing tension of fossil energy and the increasing importance of environmental protection, clean, efficient, hydrogen-fueled fuel cell (Fuel Cell, FC) technology has become a new energy source for sustainable development in the future, and is increasingly valued by governments around the world . [0003] Proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell, PEMFC) is as following alkaline fuel cell (AFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC) and solid oxide fuel cell (SOFC) The fifth generation of fuel cells developed later. Due to the use of solid-state electrolyte polymer film as the electrolyte, it has the characteristics of high energy conversion rate, low-temperature start-up, and no electrolyte leakage. Therefore, it is recognized as the mos...

AI Technical Summary

Problems solved by technology

[0006] At present, the hydrogen production technology of hydride hydrolysis still has the following disadvantages: (1) It is difficult to control the rate of chemical reaction after the liquid hydride contacts with the catalyst; (2) The pressure adjustment of the device system requires additional equipment, which makes the structure of the device system Complicated and inconvenient to operate

However, the structure of the hydrogen generator is complicated, and its catalytic reactor is placed in the fuel tank as a whole, so it is very difficult to replace the catalyst, and once the elastic device fails, the reaction is difficult to be stopped in time, and the safety is poor
