Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a methanol-water hydrogen production power generation system and a hydrogen production power generation method. Background technique [0002] Hydrogen is one of the most ideal energy sources in the 21st century. When burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water without ash and waste gas. pollute the environment; while coal and oil combustion mainly produce CO 2 and SO 2 , which can produce the greenhouse effect and acid rain respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously produce hydrogen and never run out. The distribution of hydrogen is very wide, and water is a large "warehouse" of hydrogen, which contains 11% hydrogen. There is about 1.5% hydrogen...

Problems solved by technology

In the prior art, the fuel cell cooling system mainly includes a water circulation cooling system, and its main components include a heat sink in the fuel cell, a water pump, and related supporting pipes and supporting water tanks. As a result, the fuel cell power generation system still has the following problems: First, during the continuous operation of the fuel cell, the temperature of the water in the fuel cell cooling system will become higher and higher, and the cooling efficiency of the fuel cell cooling system will continue to decrease. Affect the working stability of the fuel cell. For this reason, the fuel cell cooling system also needs to use radiators such as fans to dissipate heat from the water, which consumes energy. Second, the heat generated by the fuel cell is wasted and not utilized. The overall power generation efficiency of the fuel cell power generation system is not high, and energy waste is serious
