[0005] However, in the above test process, since the gas flow collected by the gas flow meter does not immediately enter the membrane electrode at the fuel cell, the voltage between the membrane electrode at the fuel cell at the current moment and the gas flow at the current moment No correspondence, that is, the voltage of the membrane electrode at the fuel cell at the current moment may be the gas flow collected by the gas flow meter at the previous moment. This method will cause errors in the linearity test of the membrane electrode of the fuel cell

The invention provides a test method and device suitable for a fuel cell membrane electrode and a storage medium, and the method comprises the steps: collecting the air inlet flow of an air inlet at the current moment based on a flowmeter to obtain the current air inlet flow information, and collecting the gas humidity information of a gas humidifying pipeline at the current moment based on a humidity sensor, collecting gas heating information of the gas heating pipeline at the current moment based on a temperature sensor; acquiring air inlet pipeline length information, humidifying pipeline length information and heating pipeline length information to obtain total length information; on the basis of the attribute information of the gas at the current moment, the current gas inlet flow, the gas humidity information and the gas heating information, the average flow information of the inlet gas is obtained, and compensation time information is calculated according to the total length information and the average flow information; extracting moment information of the current moment, and obtaining predicted time information based on the moment information of the current moment and the compensation time information; and enabling the current air inlet flow at the current moment to correspond to the electric energy information of the membrane electrode when the time information is predicted.
Description
technical field [0001] The invention relates to the technical field of fuel cell testing, in particular to a testing method, device and storage medium suitable for fuel cell membrane electrodes. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials, and at the same time There are no mechanical transmission parts, so the emission of harmful gases is very small, and the service life is long. It can be seen that from the point of view of saving energy and protecting the ecologic...
