The invention provides a heat energy recovery internal combustion engine. The device comprises a combustion chamber, an air inlet channel, a spark plug, an air pressure supplementing cavity and a hydrogen inlet channel. According to the internal combustion engine, in the air inlet process of the air piston, hydrogen exhausted by the vehicle-mounted fuel cell is synchronously injected into the combustion chamber through the hydrogen inlet channel, so that the hydrogen is mixed with gasoline; and at the later stage of the air inlet process of the air piston, part of mixed gas in the combustion chamber is pumped out through suction of the piston in the air pressure supplementing cavity and temporarily stored in the air pressure supplementing cavity to serve as supplementary fuel in the acting combustion process of the combustion chamber. After the piston reaches the peak position of the compression stroke, the mixed gas is supplemented into the combustion chamber until the spark plug ignites to block the air pre
