Provided is an electrochemical device having an electron source and a hydrogen peroxide solution for reaction to accept the electrons, the device with an anode compartment and a cathode compartment, including (a) a cathode electrode having an area, which can be adjustable, in contact with the cathode compartment of AC; and (b) an anode electrode having an area, which can be adjustable, in contact with the anode compartment of AA, wherein either the cathode or anode electrode area or both are adjustable, such that AC/AA=EAR is adjustable, and wherein, where jEC is the anode current provided by the electron carrier, and jTOS is a diffusion-limited current density for a reaction by oxygen in an oxygen saturated said hydrogen peroxide solution, EAR is selected such that either (a) EAR<=JEC/jOS, or (b) jEC/EAR approaches the value of jTOS.
