Fig. 5: Theoretical and observed water evolution inside the single serpentine fuel cell.

a and b The theoretical and experimental water volumes for different current densities and potentials as dashed and solid lines, respectively, normalised to an active area of 1 cm2. c and d Compare theoretical and experimentally determined time-dependent water increases over the current and potential.
