Abstract : Further tests were made on the porous, flow through electrodes described previously. It was confirmed that for methanol, formaldehyde and formate at high current densities, the observed limiting currents are considerably less than theoretical values. The same electrodes using the stannous-stannic couple as reactant gave exact agreement between the observed and limiting current. It is concluded that the limiting factor present for the hydrocarbon fuels is not a mass transport factor. In general, the theoretical predictions of the effect of flow-rate, concentration on the polarization curves are valid at lower current densities, but fail near the region of the abnormal limiting current.
