| 摘 要： | 以质子交换膜燃料电池实际应用为背景,研究了在反应物低化学计量比下,质子交换膜燃料电池不同温度、压力下的性能。得到了电池温度,压力对反应物化学计量比的影响。实验结果表明,反应物化学计量比1.0的电池性能低于足量反应气体工况下的电池性能;化学计量比为1.3时,电池能够在预期电流强度下稳定运行;反应气体的传质过程影响反应所需的化学计量比;当提升压力至0.13 MPa,化学计量比1.0的电池性能与足量反应气体工况下的性能相当。

| 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. |
