ABSTRACT

In this paper an alkaline fuel cell (AFC), which was developed using nickel electro-catalyst for hydrogen oxidation process is reported. Pumice plate with porosity of 71% was used as an electrode substrate, and it was made by depositing conducting carbon using CVD process. Nickel metal was electroplated over the carbon deposited pumice plate. Carbon nanotubes were deposited over the electroplated nickel to prevent nickel from getting corroded by KOH solution (electrolyte). It is observed that 1.9 wt% nickel gives the best stability giving 300 mA/cm2 current density at 980 mV as hydrogen dissociation voltage. I-E characteristics and chronoamperometric studies of half and full cells are also reported.
