United States Patent | 5,618,393 |
Law, Jr. ,   et al. | April 8, 1997 |
The invention relates to an electrochemical cell which has an electrode, a membrane disposed in contact with one side of the electrode and a mass flow field disposed on the other side of the electrode for directing fluid to and away from the electrode. The mass flow field comprises glassy carbon. The cell of the present invention is particularly useful in converting anhydrous hydrogen halide, in particular, hydrogen fluoride, directly to essentially dry halogen gas, such as dry fluorine gas. Alternatively, the cell may be used to convert an aqueous reactant.
