To enhance efficiency of heat management of an electrochemical engine.
An electrochemical engine is equipped with a storage tank, containing a hydrogen storing material that absorbs hydrogen at a hydrogen absorbing temperature, and liberates hydrogen at the liberating temperature. A stack generates electricity, and heat as a by-product, through the use of liberated hydrogen. A flow circuit of a main coolant circulates from a radiator to an original position through a stack and a tank, with a distributing valve among them. A bypath line for a coolant extends from a valve for distribution to a radiator. A secondary heat from the stack is transmitted to a tank through a circuit for a liquid, where it liberates hydrogen by heating a hydrogen storing material. A heat generator and a pump are included in a loop for a coolant for the over heating. The said loop has a bypath valve to let a coolant stand alone between the tank and the radiator. A coolant in the loop is heated by a heat generator and circulated, to liberate more hydrogen gas from the hydrogen storing material.
