Other AbstractThe invention relates to a double-unit backup controller of a proton exchange membrane fuel cell. A master controller processor and an alternate controller processor are both connected with a power supply module, a data storage module, a master/alternate controller switching module; the master controller processor is also connected with the alternate controller processor and a communication module; the master/alternate controller switching module is connected with a data acquisition module and a driving output module. The method comprises the following steps that the master controller processor monitors a fuel cell device in real time, and regularly sends data of a fuel cell sensor to the alternate controller processor for backup; when the master controller processor malfunctions, the alternate controller process backs up the information of the fuel cell sensor by the master/alternate controller switching module and turns off the device. According to the invention, double-unit standby redundancy design is adopted; when the master controller malfunctions, the alternate controller can replace in real time so as to complete the necessary control operation, so that the system is prevented from being in the out-of-control state; the double-unit backup controller of the proton exchange membrane fuel cell has the characteristics of performance stability and high reliability.
