| Outline of Final Research Achievements |
Fuel cells that extract electric energy from hydrogen towards a clean energy society of the next generation attract much attention. At present, research on anhydrous organic solid proton electrolytes with environmentally harmonious and utilizing in the middle temperature range are required for fuel cell. In this work, we focused on co-crystals of imidazole-dicarboxylic acid as an anhydride acid-base-type purely organic proton conductors. Based on the relationship between the bulk intrinsic proton conductivity without grain boundary and the crystal structure, the multidimensional hydrogen bonding network and the small difference in pKa between acid and conjugated base greatly contributes to the proton conductivity and suggests next material design.
