Definitions
- FIG. 11 is a graph of polarization curves for MEAs containing additional oxygen-reducing catalyst layers of the present invention.
- suitable gases for the first processing environment include nitrogen-containing gases, oxygen, water vapor, hydrogen, argon, and combinations thereof.
- gases for the first processing environment include nitrogen-containing gases, such as nitrogen, ammonia, nitrogen-containing volatile organic compounds (e.g., pyridine, acetonitrile, pyrrole, pyrrolidine, and quinoline) and combinations thereof.
- substrate 12 is then passed through the PVD system (step 22), thereby exposing substrate 12 to the first processing environment.
- suitable materials for substrate 12 include nanostructured thin film substrates (e.g., substrates disclosed in Parsonage et al, U.S. Patent No. 5,338,430, and in Debe, U.S. Patent Nos.
- hydrogen fuel H 2
- MEA 58 may alternatively use other fuel sources, such as methanol, ethanol, formic acid, and reformed gases.
- the fuel passes through gas diffusion layer 70 and over anode catalyst layer 68.
- the fuel is separated into hydrogen ions (H + ) and electrons (e ).
- Electrolyte membrane 66 only permits the hydrogen ions to pass through to reach catalyst layer 10 and gas diffusion layer 72.
- the electrons generally cannot pass through electrolyte membrane 66.
- the electrons flow through external electrical circuit 60 in the form of electric current. This current can power an electric load, such as an electric motor, or be directed to an energy storage device, such as a rechargeable battery.
- the carbon powder was agitated during the sputtering by turning the particle agitator shaft at 10 RPM. After a total of 0.23 kWH was expended, the reaction was stopped and the chamber was backfilled with air and the sample was removed from the reactor. The target weight loss after this treatment was 0.95 grams.
- the iron-treated film was placed in a fused silica boat and placed in a tube furnace for the thermal treatment.
