Three different types of hybrid direct carbon fuel cells were investigated for direct electrochemical oxidation of carbon black. One where anode-supported with a Ni/YSZ (yttria stabilized zirconia) anode and two cathode supported cells with either a NI/YSZ anode or a praseodymium-doped cerium oxide anode. The middle one performed the best, probably due to better contact to anode with the fuel and the presence of metallic nickel.
