a Current density at reverse bias of 0.2 V as a function of junction thickness for different WD rate constants in the junction. b Polarization curves in reverse bias for different junction thickness with WD rate constant kf = 100 s−1. Similar results using the reported diffusion coefficients for H+ an OH− along with the fixed ion concentration in the membranes estimated based on the manufacturer specifications are in Supplementary Fig. 4. See Methods for more information.
