Abstract

The invention discloses a fuel cell prepared based on methanol and water renormalization. The fuel cell comprises an evaporation chamber; an evaporator is arranged in the evaporating chamber; the evaporating chamber is connected with a renormalization chamber; the renormalization chamber is connected with a high temperature fuel cell stack through a micro channel; an anode and a cathode are arranged in the high temperature fuel cell stack; a proton membrane is arranged between the anode and the cathode; and the anode is provided with a catalyst. The advantages are that: hydrogen energy carriedby methanol is converted into electric energy, hydrogen energy carried by water is converted into electric energy, extraction and utilization of energy in water is realized, waste of heat utility isavoided; cycle utilization can be realized; and hydrogen production efficiency and methanol conversion rate are increased.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a fuel cell prepared based on methanol and water reforming, and belongs to the field of fuel cells. Background technique [0002] At present, the most effective way to solve these problems is to develop a micro-hydrogen production reaction system to provide hydrogen fuel for fuel cells, and the production of hydrogen is not limited by storage, transportation, and safety, and can be produced at any time and used at normal pressure. At present, most of the research is to generate hydrogen through the reforming reaction of low-carbon alcohols (such as methanol and ethanol). There are three main methods of reforming reactions, namely steam reforming, partial oxidation reforming and automatic thermal reforming. At the same time, a compact on-site hydrogen production fuel processing system is adopted. With its compactness, high efficiency and low cost, it has broad application prospects in the instantane...
