Benefits of technology

[0022]According to the present invention, as the effect of insulation is improved by forming the heat insulating zone, it is possible to make the apparatus more compact than conventional electrolytic apparatuses. Accordingly, the heat discharge to the outside can be dropped, and the electrolytic cell is heated effectively, as the result, the waste of energy can be minimized by heat exchanging means. Also, as the heat insulating zone is decom

Problems solved by technology

When the pressure of heat insulating zone is less than 10 kPa, the thermal conductivity by gases cannot be lowered, which decreases the efficiency
