ABSTRACT:
A proton conductive solid polymer electrolyte includes a polypyridobisimidazole-based compound and at least an acid. The proton conductive solid polymer electrolyte can be used to make a fuel cell with good power generation over a long period of time under a relative humidity of about 0% to about 50% at an operating temperature of about 100° C. to about 300° C.
