Abstract: 
In the current studies a miniature silicon wafer fuel cell (FC) using l-ascorbic acid as fuel was developed. The cell employs l-ascorbic acid and air as reactants and a thin polymer electrolyte as a separator. Inductively coupled plasma (ICP) silicon etching was employed to fabricate high aspect-ratio columns on the silicon substrate to increase the surface area. A thin platinum layer deposited directly on the silicon surface by the sputtering was used as the catalyst layer for l-ascorbic acid electro-oxidation. Cyclic voltammetry shows that the oxidation of l-ascorbic acid on the sputtered platinum layer is irreversible and that the onset potentials for the oxidation of l-ascorbic acid are from 0.27 V to 0.35 V versus an Ag/AgCl reference electrode. It is found that at the room temperature, with 1 mol/L l-ascorbic acid/PBS (phosphate buffered solution) solution pumped to the anode at 1 ml/min flow rate and air spontaneously diffusing to the cathode as the oxidant, the maximum output power density of the cell was 1.95 mW/cm2 at a current density of 10 mA/cm2.
