Portable smart low-cost proton conductive gel paste electrolytes, capable of retaining their properties over a few months and of being stored, are of significance in the context of portable fuel cell power sources. A low-cost, sol gel derived inorganic gel paste electrolyte with an optimum phosphorous to silicon ratio of five, whose proton conductivity exceeds Nafion in the broad temperature range of 50–180 °C, is reported herein. The fuel cell assembled with this gel paste coated on a glass mat, operating at a temperature of 160 °C, produces a maximum current density of >1 A cm⁻², a power density of >210 mW cm⁻² and offers stable durable operation up to 29 hours under a 50 mA cm⁻² load. The significance of these findings is that the gel paste may be used to replace conventional liquid and membrane electrolytes in fuel cells and be applied in new generation electronics with portable fuel cells.

便携式智能高质子传导性全无机凝胶糊状电解质，具有最佳的磷硅比，可增强燃料电池的耐用性†

在便携式燃料电池电源的背景下，便携式智能低成本质子导电凝胶糊状电解质能够在几个月内保持其性能并能够被存储，这是很重要的。本文报道了一种低成本的溶胶凝胶衍生的无机凝胶糊状电解质，磷与硅的最佳比例为5，在50-180°C的宽温度范围内，其质子传导率超过Nafion。在160°C的温度下运行时，将这种涂有凝胶糊的燃料电池组装在玻璃垫上，产生的最大电流密度> 1 A cm ^-2，功率密度> 210 mW cm ^-2，并提供稳定的耐用性在50 mA cm ^-2下最多可运行29小时加载。这些发现的意义在于，该凝胶糊剂可以用来代替燃料电池中的常规液体和膜电解质，并可以应用于带有便携式燃料电池的新一代电子设备中。
