Abstract: An ion exchange membrane electrolyzer includes an elastic body configured to press on a second electrode so as to bring an ion exchange membrane into close contact with electrodes. The elastic body includes a fixed part fixed to one of a base part and the second electrode, and an elastic part that extends from the fixed part, and is configured to press on the second electrode by elastic deformation. The elastic part is formed so as to be plate-like and formed so as to be corrugated along a direction in which it extends, such that a top part on one side is in contact with the base part and a top part on the other side is in contact with the second electrode.

Abstract: A method for rapid cooling of high temperature reaction gases obtained by ermal cracking of hydrocarbons, which comprises conducting an indirect heat exchange between a high temperature reaction gas obtained by thermal cracking of a hydrocarbon and a molten metal maintained at a prescribed temperature, lest heavy components in the high temperature gas be substantially condensed. In this method, the molten metal can be circulated by the use of a pressurized inert gas. In practice of this method, there can be effectively used a high temperature reaction gas cooling apparatus comprising a double-tubular heat exchanger, a cooling tank connected to said heat exchanger, and an inert gas circulating passage connected to a conduit connecting said heat exchanger and said cooling tank.
