Embodiment

[0035] The hydrogen production integrated system for kilowatt-level fuel cells to provide hydrogen on site in the present invention is mainly composed of a series of reactors, heat exchangers, mixers, raw material storage tanks and air compressors, etc. ( figure 1 ). The series of reactors include: reforming reactor R1, shift reactor group R2, CO purification reactor group R3 and catalytic combustion evaporator R4.

[0036]During implementation, a part of the reformed fuel in the storage tank S2 and the air from the air compressor S3 are mixed into the catalytic combustion evaporator R4, and the catalytic combustion reaction is carried out in the catalytic combustion evaporator R4 and a large amount of heat is emitted, and a large amount of high-temperature combustion gas The heat is transferred to the reforming reaction raw material through the heat exchanger H4, and the reforming reaction raw material after heat exchange with the high-temperature combustion gas in the heat e...

Abstract

The present invention provides a hydrogen generation integration system for on-site provision of hydrogen for a kW-scale fuel cell. The whole system comprises a reforming reactor, a transform reactor set, a CO purifying reactor set, a catalytic combustion evaporator, a heat exchanger, a mixer, a raw material storage tank, an air compressor and the like. Raw materials of the reaction pass through the reforming reactor to produce hydrogen-rich mixed gas, and the mixed gas enters the CO transform reactor and the CO purifying reactor to reduce the CO content in the hydrogen-rich mixed gas to 0-50 ppm. The hydrogen generation integration system of the present invention is especially suitable for the on-site provision of the hydrogen for the 1-200 kW-scale fuel cells.

Description

technical field [0001] The invention relates to an integrated system for reforming hydrogen production, which is especially suitable for providing hydrogen-rich gas on site for 1-200kW fuel cells. Background technique [0002] Proton exchange membrane fuel cells (PEMFC) use hydrogen as fuel, and directly convert chemical energy into electrical energy through electrode reactions, with high energy conversion efficiency and low environmental pollution. At present, there are two types of PEMFC hydrogen source technologies: one is pure hydrogen carried by fuel cells; the other is on-site hydrogen production from hydrogen-rich fuels. Due to the high price of pure hydrogen, poor safety, and difficulties in the transportation, storage and refilling of pure hydrogen, the use of pure hydrogen inevitably limits the scale application of fuel cells. Liquid-phase alcohol and hydrocarbon reforming on-site hydrogen production technology is the most realistic hydrogen source technology for ...
