CONSTITUTION: A plurality of plate-like electrolysis cells are disposed adjacent one another in a stack, are in electrical contact, and each comprise a housing consisting of two half-shells of electrically conductive material with outer contact strips on at least one housing rear wall. The anode and the cathode are separated from each other by a partition wall, are disposed parallel to one another and are connected in an electrically conductive manner to the respective associated rear wall of the housing by means of metal reinforcements. To achieve the surfaces through which current flows to be as large as possible, the metal reinforcements take the form of webs (10) which are aligned with the contact strips (7) and whose side edges (10A, 10B) abut the rear wall (3A, 4A) and the anode (8) and cathode (9) over the height of the rear wall (3A, 4A) and the anode (8) and cathode (9).

Abstract: PURPOSE: A tunneling device and software for data communication is provided to access network resources or computer system installed inside security firewall without copying an object or resource of inside the firewall, responding to a request from outside the firewall. CONSTITUTION: An inside sever comprises and stores a trusted socket table and outputs a copy of socket table via a control contact to outside sever with a specific control contact. Receiving a request of outside tunneling, the outside sever determines it to include in available socket table. Unless the request received is available, it is rejected. And if the request is available, it makes a process or task processing data transmission outside element related to the demand object. The task comprises data contact between request object and itself and transmits the request via control contact to inside sever. The inside sever operates a process, and the process comprises data contact segment from host object to firewall computer, and orders firewall computer to contact with outside sever task. Therefore data contact between inside host object and request object of outside is accomplished.
