ELECTROLYSIS DEVICE

An opening in the upper part of an electrolysis tank main body is closed by a first cover body with a sealing member sandwiched therebetween. An opening in the first cover body is closed by a second cover body with a sealing member sandwiched therebetween. The opening in the first cover body is smaller than the opening in the electrolysis tank main body. A partition wall that divides the inside of the electrolysis tank main body into a positive electrode chamber and a negative electrode chamber is provided integrally on the lower surface of the second cover body. The positive electrode chamber is disposed in an area on the inside of the sealing member. A positive electrode is attached to the second cover body inside of the positive electrode chamber, and the negative electrode is formed on the inside surface of the electrolysis tank main body. An electrolyte bath inside the electrolysis tank undergoes electrolysis, thereby generating fluorine gas in the positive electrode chamber. A plurality of round through holes may be formed in a liquid partition wall. Each through hole has an upper surface that extends upward at a slant from an end part on the positive electrode chamber side to an end part on the negative electrode chamber side. The diameter of the positive electrode side end of the through holes in the vertical direction is set to a size such that the electrolyte bath can pass through and bubbles of fluorine gas and hydrogen gas cannot pass through. The diameter of the through holes in the vertical direction on the negative electrode side end is larger than the diameter of the through holes on the positive electrode side end. Selon la présente invention, une ouverture dans la partie supérieure d'un corps principal de réservoir à électrolyse est fermée par un premier corps de couvercle, un élément d'étanchéité étant intercalé entre ces derniers. Une ouverture dans le premier corps de couvercle est fermée par un second corps de couvercle, un élément d'étanchéité étant intercalé entre ces derniers. L'ouverture dans le premier corps de couvercle est plus petite que l'ouverture dans le corps principal de réservoir à électrolyse. Une paroi de séparation, qui divise l'intérieur du corps principal de réservoir à électrolyse en une chambre d'électrode positive et en une chambre d'électrode négative, est disposée d'un seul tenant sur la surface inférieure du second corps de couvercle. La chambre d'électrode positive est disposée dans une zone sur la partie int
