Abstract

The invention relates to a hydrogen generator and application thereof. The hydrogen generator is formed by a first medium comprising a recombination zone, an oxidation zone and a preheating zone, wherein the recombination zone is used for accommodating a recombination accelerant so as to carry out the steam recombination reaction of a hydrogen-producing raw material to generate hydrogen; the oxidation zone is used for carrying out heat release oxidation reaction so as to provide a heat source, and a first oxidation accelerant exists in the oxidation zone; the heat source provided by the oxidation zone supplies heat energy to the preheating zone and the recombination zone so as to firstly preheat the hydrogen-producing raw material in the preheating zone and subsequently carry out the steam recombination reaction in the recombination zone; first media exist among the recombination zone, the oxidation zone and the preheating zone at the intervals of the shortest distance of at least 0.5mm; and the coefficient (K) of heat conduction of the first media is at least 60W/m-K. The carbon monoxide content of a hydrogen-contained gas mixture prepared by the hydrogen generator is quite low, therefore, the gas mixture can be directly applied to common fuel.

Description

technical field [0001] The invention relates to a hydrogen generator; in particular, it relates to a hydrogen generator providing hydrogen mixed gas with low carbon monoxide content and its application. Background technique [0002] High-purity hydrogen is an important fuel source for many energy conversion devices. For example, a fuel cell known as a "green generator" uses high-purity hydrogen as a fuel to react with oxygen (or air) to generate electricity by directly converting chemical energy into electrical energy. [0003] The current method commonly used to produce hydrogen is steam reforming reaction (steam reforming reaction, SRR), which is to make steam and alcohols (such as methanol, ethanol) or hydrocarbons (such as methane, hexane) in the presence of SRR catalyst The reaction produces the desired hydrogen gas mixture. Wherein, since SRR is an endothermic reaction, a heat source must be provided to satisfy the heat required for the reaction. For example, an exo...
