A metal-air battery includes an anode portion including a metal; a cathode portion including a porous layer, wherein the porous layer includes a reduced non-stacked graphene oxide; and an electrolyte disposed between the anode portion and the cathode portion.

Metal-air battery and method of manufacturing the same

A polybenzimidazole-base complex includes a polybenzimidazole-based material and a base, wherein a peak corresponding to NH of an imidazole ring of the polybenzimidazole-based material does not appear at a chemical shift of 12 to 15 ppm in aH nuclear magnetic resonance (H-NMR) spectrum of the polybenzimidazole-base complex. A crosslinked material may be formed as a polymerization product of a polybenzimidazole-base complex and a benzoxazine-based monomer. The crosslinked material may be used an electrolyte membrane for a fuel cell comprising the crosslinked material, and a fuel cell may include the electrolyte membrane.
