溶胶-凝胶衍生的高质子传导性P2 O 5-SiO2-PMA（磷钼酸，H3 PMo 12 O 40 nH 2 O）玻璃作为电解质用于在30 °C下在阳极用基于H2的气体和阴极用基于O2的气体加湿下的H2/O2燃料电池性能。通过测量电池电位-电流密度图来评价电极的性能。虽然极化曲线产生与基本电池性能相关的数据，但可以通过使用阻抗分析仪进行电化学测量来找到更详细的信息。功率密度显示出与电流密度相似的模式。在30°C和30%湿度下，使用0.1 mg/cm 2的Pt/C负载电极和P2 O 5-SiO2-PMA（4-92-4 mol %）实现了16.2 mW/cm 2的最大功率密度值。玻璃膜在这里起着关键作用，作为质子传输的电解质介质和屏障，以避免燃料和氧气之间的直接接触。
Sol-gel derived high proton conducting P2O5-SiO2-PMA (phosphomolybdic acid, H3PMo12O40 nH2O) glasses as electrolyte were used for the H2/O2 fuel cell performance at 30 °C under humidification with H2- based gas at the anode and O2- based gas at the cathode. The performance of the electrode was evaluated by the measurement of cell potential-current density plots. While the polarization curve yields data related to basic cell performance, more detailed information can be found by electrochemical measurements with an impedance analyzer. The power density shows a similar pattern to current density. The maximum power density value of 16.2 mW/cm2 was achieved with 0.1 mg/cm2 of Pt/C loading electrode and P2O5-SiO2-PMA (4-92-4 mol %) at 30°C with 30 % humidity. The glass membrane here plays a key role as electrolyte medium for proton transport and barrier to avoid the direct contact between fuel and oxygen.
