Highly-bendable, proton-conductive silicate glass electrolytes integrated with polyimide nonwoven fabrics for medium-temperature/low-humidity proton exchange membrane fuel cells |
| 초록 |
The highly-bendable, proton-conductive silicate glass electrolyte integrated with the PI nonwoven fabric (b-SS glass electrolyte) has been developed for potential use in medium-temperature/low-humidity PEMFCs. The b-SS glass electrolytes are fabricated via in-situ sol-gel synthesis of 3-trihydroxysilyl-1-propanesulfonic acid (THPSA)/3-glycidyloxypropyl trimethoxysilane (GPTMS) mixtures inside PI nonwoven substrates serving as a porous reinforcing framework. Owing to this structural uniqueness, the b-SS glass electrolytes provide noticeable improvements in mechanical bendability and membrane thickness, in comparison to typical bulk silicate glass electrolytes that are thick and easily fragile. Another salient feature of the b-SS glass electrolytes is the excellent proton conductivity at harsh measurement conditions of medium-temperature/low-humidity, which is highly important for PEMFC-powered electric vehicle (EV) applications. |
