Cellulose Nanocrystal-Based Solid Electrolyte With Superior Dimensional Stability for Alkaline Fuel Cell Membranes (PPT)

摘要

PVA/silica/CNC composite films were prepared for AEM Fuel Cells. As synthesized membrane (e.g., film 40B) exhibited lower conductivity-normalized swelling ratio compared to state of the art. Most importantly, CNC is predicted to work well with other existing AEMs to reduce their swelling ratio. Further modification of CNC with suitable cations may result in even greater hydroxide conductivity.
