Description
Technical Field
The invention relates to the technical field of air filters, in particular to a chemical adsorption-based air filter of a fuel cell vehicle.
Background
The current use of fossil fuels meets 80% of the world's energy needs, but there are two serious problems with the continued use of fossil fuels: firstly, the reserves are limited and will be exhausted sooner or later; secondly, the use of fossil fuel has caused a series of serious environmental problems such as global warming, ozone depletion, acid rain, and the like, and the adoption of a novel clean and efficient energy source is urgent. Hydrogen is the lightest, cleanest, most efficient fuel, which can directly convert chemical energy into electrical energy in a fuel cell, with extremely high energy utilization. The proton exchange membrane fuel cell is the first choice of the vehicle fuel cell by virtue of the advantages of high power density, low working temperature, small volume, quick start and the like. However, the proton exchange membrane fuel cell has extremely high requirements on air during operation, and toxic and harmful substances such as sulfur, carbon monoxide and the like can cause catalyst poisoning and inactivation. In addition, to increase the power of the fuel cell stack, the fuel cell needs to be operated at a higher pressure, which is provided by a centrifugal compressor. The requirements of the centrifugal compressor on air suction are also strict, and the blades of the air compressor rotating at high speed can generate abnormal vibration due to particles, liquid drops and the like in the air, and even the air compressor can be damaged in serious cases; therefore, the air filter must effectively block and intercept various liquid drops and particles in the sucked air, and can better absorb toxic and harmful gases in the air, and strictly and thoroughly filter the air entering the air compressor and the fuel cell pack, the fuel cell passenger car is a new-technology passenger car taking hydrogen as an energy source, and is generally regarded by the advantages of energy conservation, zero emission, no pollution, high efficiency, low noise, high reliability and the like, but a power source, namely the fuel cell, is very fragile and is easily influenced by harmful substances in the air, so that the performance of the fuel cell passenger car is seriously reduced. This is because the fuel cell directly uses oxygen in the air as an oxidant, and if impurities in the air enter the fuel cell, the impurities will cause irreversible damage to the cathode catalyst of the fuel cell, thereby causing the performance of the fuel cell to be significantly reduced. Therefore, the air cleaner is an essential component for the fuel cell.
