FIG. 1.

Schematic diagram of the three-electrode cell used in the experiments. The surface area of the Pt anode (cathode) is . The contents of the anode compartment were constantly stirred by a magnetic stirrer (not shown).

FIG. 2.

(Color online) Time needed to produce the same amount of and the current in the circuit are plotted against the applied potential (vs SHE) for run 2. The lines joining the points are for visual aid. The estimated error for is .

Image of FIG. 3.
FIG. 3.

(Color online) Quantity representing the amount of hydrogen produced per W h of energy consumed is plotted against potential . Runs 1 and 2 were carried out using a carbon concentration of of the electrolyte under similar conditions. For comparison, data without added carbon are also shown. Lines connecting the points are drawn for visual clarity.

FIG. 4.

(Color online) produced per minute for run 2 is plotted against the current measured in milliamperes for experiments with ( carbon) and without carbon. Lines connecting the points are drawn for visual clarity.

Image of FIG. 5.
FIG. 5.

(Color online) Variation of the quantity ( produced per W h) is plotted against the carbon concentration for three operating potentials . Lines joining the points are drawn for visual clarity.

Tables
