METHOD FOR ADJUSTING WATER CONTENT OF FUEL CELL AND METHOD FOR DETERMINING HUMIDIFICATION PARAMETER MAP

摘要

Provided are a method for adjusting the water content of a fuel cell and a method for determining a humidification parameter map. The method for adjusting the water content of a fuel cell comprises: firstly establishing a monolithic cell output voltage model; secondly, under a determined working condition, according to the monolithic cell output voltage model, determining an anode excess humidification boundary line and a cathode excess humidification boundary line; and finally, determining a fuel cell humidification parameter map jointly according to the anode excess humidification boundary line and the cathode excess humidification boundary line. The fuel cell humidification parameter map obtained by means of the method can help an operator prevent poor humidification, and also indicates the optimization direction of the current humidification parameter to the operator.
