Abstract
One-compartment hydrogen peroxide fuel cells with Co, Cu, and Fe phthalocyanine (PC) and iron nitride (FexN) as cathodes and Ni anode have been investigated as sustainable energy sources. The cells were operated under acidic conditions and at room temperature. The potentials for onset of the catalytic currents in these cells were determined via cyclic voltammograms. The reduction current onset potentials of FePC, CoPC, CuPC and FexN were 0.56 V, 0.42 V, 0.51 V and 0.57 V, respectively. Potentialcurrent linear sweep voltammetry was utilized to determine the open circuit potentials (OCP) and the power densities the fuel cells. The OCPs for Co, Cu, and Fe phthalocyanines and FexN were 0.47 V, 0.57 V, 0.56 V and 0.58 V, respectively. The maximum output power densities of FePC and CoPC, CuPC, and FexN were 3.41mWcm−2, 0.39 mWcm−2, 0.39 mW cm−2 and 0.76 mW cm−2, respectively. These power densities are suitable for powering micro-devices.
