Enhanced Performance of Membraneless Sodium Percarbonate Fuel Cells

Figure 3

Variations of cell performance with five assigned fuel concentrations of sodium percarbonate in sodium hydroxide solution: (a) the polarisation curves; (b) the corresponding power density curves.

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

(b) The curved lines indicate that the maximum power density is almost same for the variation of fuel concentration from 0.75 M to 0.075 M
