Abstract

The invention discloses a pure hydrogen catalytic device with an integrated multi-sleeve structure for various hydrocarbon fuels, and a PEMFC power generation system. The pure hydrogen catalytic device is of a cylindrical structure, the interior of the pure hydrogen catalytic device is of a three-layer structure, the outermost layer is a combustion reaction chamber, the intermediate layer is a reforming catalytic reaction chamber, the innermost layer is a water gas reaction chamber, and a partition wall is arranged between every two adjacent layers; the combustion reaction chamber is used forsupporting a combustion catalyst, the reforming catalytic reaction chamber is used for supporting a reforming catalyst, the water gas reaction chamber is used for supporting a water gas reaction catalyst, and a hydrogen permeation membrane is arranged in the water gas reaction chamber; and the reforming catalytic reaction chamber communicates with the water gas reaction chamber, a product generated by the reforming catalytic reaction chamber enters the water gas reaction chamber to continuously react, and generated hydrogen is purified through the hydrogen permeation membrane and collected. The invention promotes the improvement and solution of hydrogen preparation, storage and transportation and logistics supply difficulties and the like in the PEMFC technology.

Description

technical field [0001] The invention belongs to the technical field of energy power generation, and in particular relates to a pure hydrogen catalytic device for various hydrocarbon fuels. Background technique [0002] A fuel cell is a new energy utilization method, which is an energy conversion device that directly converts chemical energy in fossil fuels into electrical energy. The core unit of a fuel cell is a single cell, which consists of a porous cathode, a dense electrolyte, and a porous anode. Oxygen in the cathode chamber is cracked by the catalyst and combined with the transported electrons to form oxygen ions: [0003] o 2 +4e - →2O 2- (1) [0004] Under working conditions, the electrolyte has high electronic resistance and ionic conductivity, and oxygen ions migrate through the dense electrolyte layer to the anode under the action of oxygen partial pressure difference. In the anode chamber, the fuel gas is first catalytically cracked on the surface of the ...
