The invention discloses a hybrid power device of an internal combustion engine and a fuel cell and a control method thereof, comprising an internal combustion engine power assembly, a fuel cell power assembly and a power coupling device, the power generated by the internal combustion engine power assembly and the fuel cell power The power coupling device outputs power, and the fuel cell power assembly includes a fuel cell body and an air compressor, and the air compressor communicates with the cathode air inlet of the fuel cell body; the internal combustion engine exhaust port of the internal combustion engine power assembly is set There is a turbine, and the cathode air inlet of the fuel cell body is connected with the air compressor pipeline in parallel with a booster assembly, and the turbine drives the booster assembly to inject air into the cathode of the fuel cell body. The invention utilizes the inertial potential energy of the tail gas of the internal combustion engine to supply gas to the fuel cell body, reduces the energy consumption of the air compressor, realizes the recovery and reuse of the kinetic energy of the tail gas of the internal combustion engine, and improves the energy utilization rate of the entire hybrid power device.
Description
technical field [0001] The invention relates to a hybrid power device and a control method, in particular to a hybrid power device and a control method of an internal combustion engine and a fuel cell, and belongs to the technical field of hybrid power. Background technique [0002] For traditional power machinery, its power is generally provided by an internal combustion engine by burning fossil fuels such as diesel and gasoline. Although its power, stability, and safety technologies have matured after years of development, the internal combustion engine itself has limited efficiency. , High pollutant discharge and other issues are no longer in line with the general direction of economic and environmental development. [0003] Hybrid systems are often used to solve various problems of pure internal combustion engine power systems. It generally refers to the hybridization of engines and power batteries, that is, "oil-electric" hybridization. With the rapid development of new...
