The invention relates to a direct methanol fuel cell with a heat exchange system, which comprises a fuel cell stack system and a hydrothermal management system, an air pump is arranged between the fuel cell stack system and the hydrothermal management system, the fuel cell stack system comprises a plurality of stacks, and the hydrothermal management system comprises a heat exchanger and a gas-liquid separator. A first electromagnetic valve is arranged on a pipeline between the fuel cell stack system and the air pump, a second electromagnetic valve is arranged on a pipeline between the hydrothermal management system and the air pump, and a third electromagnetic valve is arranged on an air inlet pipeline of each stack. Heat exchange of the system and the external environment is combined to the heat exchanger part, gas in the system exchanges heat with the outer surface of the heat exchanger through natural convection, and heat generated by the system is also brought out of the system. And during cold start, the
