We report a novel, simple and cheap generator-collector electrode system, employing platinum leaves, with micron-sized pores and typically 100-300. nm thickness, sandwiched with a porous track etch membrane spacer with typically 30. nm diameter pores. The electrode assembly is sealed into a polymer lamination pouch with one side 2. mm diameter exposed to electrolyte solution. The generator electrode with sweeping potential (top or bottom electrode) shows transient current with high capacitive current component. The collector electrode with fixed potential shows well-defined steady state current response at low potential sweep rates. The fabricated device shows good performance in monitoring both 1,1'-ferrocenedimethanol oxidation and proton reduction redox processes. Oxygen sensor signals are assigned to a lowering of the steady state proton reduction current.@en
