ABSTRACT:
The invention relates to fuel cell non-humidification operation, specifically to—a method on dry operation condition selection, wherein under condition of inputting dry gas, applying predetermined temperature, pressure and the input flow of the dry gas and detecting the temporary current-voltage curve of the cell. The selection method of this invention can realize steady operation of the cell under non-humidification condition and avoid the dehydration problem of the membrane under the dry gas as well as the “flood” phenomena. The present invention can be applied to not only normal temperature work condition, but also the start and run of the fuel cell under zero degree temperature condition especially. It can simplify the system of the fuel cell and therefore improve the development of the fuel cell.
