APPARATUS AND METHODS FOR ELECTROCHEMICAL HYDROGEN MANIPULATION

摘要

Apparatus and methods are provided for electrochemical hydrogen manipulation. In one example, an electrochemical cell is provided utilizing an acid doped polybenzimidazole membrane having a proton conductivity of at least 0.1 S/cm and comprising phosphoric acid in a ratio of at least 20 moles phosphoric acid to polybenzimidazole repeating unit. The polybenzimidazole membrane can be produced by a sol-gel process. Additional concepts are also described.
