Enhanced Performance of Membraneless Sodium Percarbonate Fuel Cells

Figure 4

Variations of cell performance with five assigned oxidant concentrations of sodium percarbonate in sulphuric acid solution (a) the polarisation curves. (b) The corresponding power density curves.

(a) The lines indicate that the current density increases by increasing the concentration of oxidant from 0.075 M to 0.75 M

(b) The curved lines indicate that the power density increases by increasing the concentration of oxidant from 0.075 M to 0.75 M
