Problems solved by technology

However, although the cost of the palladium composite membrane is low, the purification efficiency is high, and the output is large, the purity of the hydrogen separated by the palladium composite membrane is low. The purity of the hydrogen produced is generally only about 99%, and it is difficult to reach more than 99.999%.

Abstract

The invention provides a methanol water fuel reforming hydrogen production system. The methanol water fuel reforming hydrogen production system comprises a catalytic burner, a reformer, a water vapor converter, a selective oxidizer, a fuel storage tank and a fuel cell which are connected in sequence. The hydrogen-rich mixed gas is subjected to staged oxidation treatment through the water vapor converter and the selective oxidizer, the CO concentration in the gas is gradually reduced, and it is guaranteed that CO is completely removed. The system disclosed by the invention is short in starting time, low in energy consumption, high in hydrogen production speed, low in hydrogen production cost, high in energy conversion efficiency, environment-friendly, energy-saving and relatively high in power generation efficiency after being butted with a fuel cell stack, and the reforming hydrogen production condition can be quickly met.

Description

technical field [0001] The invention relates to the technical field of methanol reforming hydrogen production, in particular to a methanol water fuel reforming hydrogen production system. Background technique [0002] Energy and environment have become the primary issues facing the development of all countries in the world. The advent of hybrid vehicles and fuel cell vehicles using hydrogen as an energy source has provided practical and effective solutions for alleviating the energy crisis and protecting the environment. Further improving the efficiency of on-board hydrogen production to provide high-purity hydrogen sources for fuel cells has gradually become the focus of attention. Methanol has the advantages of high hydrogen content, no sulfur, low carbon monoxide CO content in the reformed product, and low reaction temperature, and has always been an important raw material for hydrogen production by reforming. The mixed gas produced by methanol steam reforming has a high...
