Problems solved by technology
However, during the operation of the fuel cell engine, the tail gas is high-humidity hydrogen-containing gas, which makes the hydrogen concentration in the tail gas easily invalid, making it impossible for fuel cell vehicles to monitor the tail gas concentration in real time, which poses a certain risk to driving safety.
At the same time, the cost of tail hydrogen concentration is high and the failure rate is high, which leads to an increase in the maintenance cost of fuel cells

The invention relates to a fuel cell vehicle tail exhaust hydrogen concentration calculation method, an exhaust control system and a use method thereof and a storage medium. The fuel cell vehicle tailexhaust hydrogen concentration calculation method can conveniently calculate the fuel cell vehicle tail exhaust hydrogen concentration, thereby providing data for the fuel cell exhaust control systemto control the hydrogen concentration in the mixed gas discharged from the exhaust gas discharge pipe. Therefore, the concentration of hydrogen in the exhaust gas of the fuel cell can be convenientlycontrolled and the exhaust gas of the fuel cell stack can reach the standard.
Description
technical field [0001] The invention relates to a method for calculating the concentration of hydrogen in tail exhaust of a fuel cell vehicle, an exhaust control system, a method for using the same, and a storage medium. Background technique [0002] Fuel cell vehicles generate electricity through the hydrogen-oxygen reaction in the fuel cell stack between the pure hydrogen in the hydrogen bottle and the oxygen in the air. Due to the reaction process, part of the hydrogen needs to be discharged outside regularly to ensure the normal and stable operation of the fuel cell. Therefore, diversion method is used to divert the discharged hydrogen into the exhaust pipe, and fully mix with the residual air in the exhaust pipe before being discharged out of the vehicle. In order to ensure safety, the regulations require that the hydrogen concentration at a distance of 10cm from the centerline of the tailpipe should not exceed a certain threshold, so a hydrogen concentration sensor is...
