Problems solved by technology
[0011] The main technical defects of the above four hydrogen fuel cell stack membrane electrode monomer voltage detection devices and methods are: the data acquisition of the membrane electrode monomer voltage is not related to the operating temperature, hydrogen pressure, oxygen pressure and other control parameters of the hydrogen fuel cell stack. Strict synchronous binding makes it impossible to accurately determine the working status of the hydrogen fuel cell stack and its management and control system

The invention discloses a device and method for synchronously detecting the voltage of single hydrogen fuel cell stack membrane electrodes, and can overcome the technical defects of an existing deviceand method for synchronously detecting the voltage of a single hydrogen fuel cell stack membrane electrode. According to the method, a synchronous trigging pulse signal is sent out by a hydrogen fuelcell stack main control unit, n single membrane electrode voltage detection units are synchronously parallelly triggered, at the same moment, the voltage data of n single membrane electrodes are synchronously parallelly collected, and according to the index serial number of the synchronization pulse signals, the main control unit strictly synchronously binds the voltage data of the single membrane electrodes with control parameters of the operating temperature, hydrogen pressure and oxygen pressure of the hydrogen fuel cell stack at the same moment, the function of accurate synchronous detection of the voltage of the single hydrogen fuel cell stack membrane electrodes can be achieved, and thus accurate verification of the entire hydrogen fuel cell stack and the working state of a management control system thereof thereof can be achieved.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment and electrical engineering, in particular to the technical field of synchronous pulse triggering, and in particular to a hydrogen fuel cell stack membrane electrode monomer voltage synchronous detection device and method thereof. Background technique [0002] With the development of fuel cell technology, hydrogen fuel cells have gradually been recognized by the industry as having broad application prospects in the field of backup power, and are considered to be the most promising new energy technology to replace batteries and diesel generators as backup power. [0003] After nearly ten years of continuous research and development, proton exchange membrane hydrogen fuel cells have made breakthroughs in terms of energy efficiency, power density, low-temperature start-up and other functional characteristics. A new wave of hydrogen fuel cell industrialization is approaching. [0004] The ...
