Objectives:

Complete test runs for performance evaluation on the 5 cm2 fuel cell, made from Nafion 1135,( 0.4mg/cm2, 20% Pt on C). Using standard current vs. Potential sweeps and Cyclic voltammetric sweeps, a fuel cell profile will be constructed.

Procedure Utilized:

Standard measurement practice of sweep the voltage from an open circuit potential to a minimum potential of 0.2V and back up to the open circuit potential. The will follow the voltage sweep file 0_01. txt . The sweep will be carried out as a Tafel sweep.

Environment:

Temperature-	70 degrees F

Barometer-	NA

Relative Humidity-	NA

Results & Conclusions:

The cyclic voltammetric sweeps have produced an electrical short, or exposed the problem, The open circuit potential of the fuel cell is at a peak of 0.6V . The fuel cell is dead and will have to be replaced.
