Example 5
Silver wires (Ted Pella Inc.) were connected to the electrodes with a conductive silver paste (Ted Pella, Inc.), and the cell was ready for testing. A manifold to supply hydrogen to the central passages defined by the glass capillary tubes was attached to the cell, and an exhaust manifold to collect hydrogen and water was also attached. Hydrogen gas was supplied through the input manifold at a rate of about 1 L/min., and the passages on either side of the cell were left open to air. Condensation of water vapor in the hydrogen exhaust manifold was observed. At a temperature of 27° C., the following performance was also observed:
