Enzyme modified electrodes for dioxygen reduction are often employed as cathodes in biofuel cells . Some concepts of biofuel cells (BFC) involve anode modified with glucose oxidase. This enzyme is not specific for glucose electrooxidation, but dioxygen acts also as a substrate. Direct enzymatic oxidation of glucose by dioxygen is a side effect for bioanode, so there is current interest to apply dioxygen-free anodic compartment in BFC. On the other side, splitting of common electrolyte to two electrodes compartments using membrane and device-case causes increase of BFC size and cost of it. Gas phase biocathode made of porous material has already been poroposed .
