Abstract
The present invention is directed to cell plates for an electrolyser module and to an electrolyser module incorporating the plates. The plates comprise an electrolysis chamber opening, at least one degassing chamber opening, and at least one gas-liquid conduit opening. The plates further comprise a channel connecting the electrolysis chamber opening and the gas-liquid conduit opening. The present invention is directed further to a process and apparatus for separating a gas-liquid mixture generated at an electrolysis cell.
Claims44
An electrolyser module comprising:
- (a) a plurality of cell plates adapted to be arranged together in sealing engagement to define at least one electrolysis cell, at least one degassing chamber, at least one gas-liquid conduit, and at least one gas-liquid channel connecting said at least one electrolysis cell to said at least one gas-liquid conduit;
- (b) at least one transfer channel for connecting said gas-liquid conduit to said at least one degassing chamber;
- (c) at least one gas outlet conduit for connecting said at least one degassing chamber to a desired location for receiving gas and at least one degassed liquid conduit for connecting said at least one degassing chamber to a desired location for receiving degassed liquid;
- and
- (d) a transfer plate, said transfer plate comprising a body, at least one electrolysis chamber opening defined in said body, at least one degassing chamber opening defined in said body, at least one gas-liquid conduit opening defined in said body, and a channel which connects the at least one gas-liquid conduit opening to the at least one degassing chamber opening.
