Abstract：
According to the forthcoming application of proton exchange membrane fuel cell, the cell performances of different temperature and pressure at low stoichiometric ratio of reactant were experimentally studied. The effect of cell temperature and pressure on stoichiometric ratio of reactant was also studied. The results indicate that: the cell performance at reactant stoichiometric ratio of 1.0 is lower than that at the condition of sufficient reactant; when the stoichiometric ratio reaches 1.3, the fuel cell can operate at the excepted current steadily; the gases mass transfer will impact the stoichiometric ratio of reactant; when the pressure is increased to 0.13 MPa, the cell performance at reactant stoichiometric ratio of 1.0 is as same as that at the condition of sufficient reactant.
