摘要： A process for coating the inner wall surface of a thin tube having an inside diameter of 0.2 to 5 mm with a resin. The tube is first filled with a resin particulate dispersion. The dispersion filling the tube is held therein by its surface tension and does not flow out. A heater is positioned about the upper end of the tube and is moved down toward its lower end to heat the tube and thereby cause minute resin particles to adhere to its inner wall surface. Then, the tube is heated in a furnace and is cooled to have its inner wall surface coated with the resin.

Each of the separators comprises an aqueous methanol solution flow-adjusting plate having grooves formed in parallel to a direction of gravity, and an oxygen containing gas flow-adjusting plate having grooves formed. A methanol tank and a water tank are connected to a supply passage through pumps respectively. The supply passage communicates through a passage to the aqueous methanol solution flow-adjusting plate. The aqueous methanol solution flow-adjusting plate is formed of a porous conductive material. Therefore, the aqueous methanol solution can be stably supplied at a uniform concentration to the entire operating surface of the anode.
