Abstract
A solid polymer electrolyte for a fuel cell has high proton conductivity, large heat resistance, an excellent mechanical strength. A fuel cell may include such solid polymer electrolyte. The solid polymer electrolyte for a fuel cell includes a proton conductive resin with side chains R1, R2, R3, and R4 that are bonded to an aromatic polyurea resin backbone.
