The invention discloses an
electric generator based on a
methanol water
hydrogen-making
system and an
electricity generation method thereof. The
electric generator comprises a
methanol water storage container, a delivery pump, a
heat exchanger, a reformer, a separation device and a fuel
cell, wherein the delivery pump is used for delivering
methanol and water to a reforming chamber of the reformer; the
heat exchanger is used for carrying out heat exchange on the low-temperature methanol and water and a high-temperature
mixed gas output from the reforming chamber; the reformer is provided with the reforming chamber and an electric heater, and the electric heater provides
heat energy for the reforming chamber; and the high-temperature
mixed gas which takes
carbon dioxide and
hydrogen as main parts is prepared in the reforming chamber, passes through the
heat exchanger and then enters the separation device to be separated to obtain the
hydrogen, and the hydrogen is delivered to the fuel
cell and subjected to electrochemical reaction in the fuel
cell to generate
electric energy, a part of the
electric energy provides
electricity for the delivery pump and the electric heater, and the rest of the
electric energy is output. According to the
electric generator, the reformer has no need of being provided with a
combustion chamber, an air inlet fan, an air
inlet channel and a
smoke window, the
heating temperature inside the reformer is easily controlled and stable, and the reformer is simple in structure, stable in operation and low in overhaul difficulty.
