Abstract

The present invention discloses a fuel battery engine air turbine compressor with energy recovery function, which comprises a electric drive compressor composed of a electric machine and an air compressor, characterized in that a console tables is also included. A revolution axis of the electric machine stretches out from left and right sides, wherein a compressor set on one end. The exit port of the compressor connects with an air intake port of the fuel battery while the other end is provided with a turbine machine. The turbine machine recovers gaseous energy in some certain temperature, dampness and pressure from the air exhaust port of the fuel battery. The energy recovered from the fuel battery air discharge is equal to 50% that of compressor consumed power, reduces watt consumption of the electric machine in the invention, and meets state requirement of energy saving and discharge reducing.

Description

technical field [0001] The invention relates to the technical field of air supply systems for fuel cell engines, in particular to an air turbine compressor for fuel cell engines. Background technique [0002] A fuel cell engine is composed of a fuel cell stack and ancillary systems. The air supply system usually needs to use an air compressor to compress the air, and the air compressor often consumes 12-20% of the output power of the fuel cell. For high-power fuel cells, the air compressors used need more power, which is not suitable for fuel cell vehicles. In order to improve the efficiency of the fuel cell engine, it is an effective technical way to recover the energy from the exhaust gas of the fuel cell. [0003] Abroad, the US Honeywell Company has developed a fuel cell engine pressurized air supply device with an exhaust expander. This device uses an electrically driven turbocharger to recover exhaust energy. See "steven chalk.Progress Report for Fuel Cell Power Syst...
