We have studied carbon materials, which have the electrical conductivity comparable to that of platinum, toward the development of inexpensive and superior electrode materials. There are various structures such as a porous carbon and a carbon nanotube in the carbon materials. In order to find out factors affecting electrochemical properties in carbon electrode materials, we focused on the graphene and measured the impedance of different kinds of graphene electrodes.
