An online observation method of nitrogen concentration in the anode of proton exchange membrane fuel cell |
| abstract |
The invention discloses a method for online observation of the nitrogen concentration of the anode of a proton exchange membrane fuel cell. Firstly, based on the gas transmembrane penetration model of the fuel cell and the anode material conservation model, a dynamic model of the anode nitrogen concentration is established, and then the average voltage degradation value between the nitrogen partial pressure and the average single cell voltage is obtained as online feedback information. Concentration dynamic model and online feedback information establish an online observer of anode nitrogen concentration, and use the online observer to obtain the anode nitrogen concentration of fuel cell. The invention solves the problem of online observation of the anode nitrogen concentration during the operation of the proton exchange membrane fuel cell engine system under dynamic conditions, and has broad application prospects in anode purification of the fuel cell engine, health detection of the fuel cell and the like. |
