In a thermoforming system for masked polymer substrate sheets, a temperature resistant, non-stick coating is applied to a sheet of a polymer substrate material. The membrane electrode assembly includes a proton-exchange membrane disposed between a first electrode and a second electrode. The processor controls the storage device according to a process. The heating device contains an expansion tank, binding pipes and heat exchangers. The LED lamp further includes an LED load and a battery powered driving circuit. A substrate is provided with either of the pair electrodes and can be strained.
