The anodic current density peak appears in BM, and the area of higher anode current
A single cell DMFC test fixture was used in this study along with the following components: an anode flow board, gasket, anode current
collector, gasket, MEA, gasket, cathode current collector, gasket, and cathode airflow board.
Considering the previously mentioned values for anode current
, DC-anode voltage, saturated output power, and the input power which is given by [P.sub.in] = [I.sub.Anode][V.sub.DC], the efficiency is 2.83%.
Therefore, significant production of anode current
is observed and the sensitivity of the electrode (nanosensor) for the measurement of low amounts of glycerol increases noticeably.
The papers were "Pushing the frontiers of anode current
density at Dubal" by Ali HAM Al Zarouni, Al Jallaf and Arvind Kumar; and "'Impact of TiB2 granules on cathode wear and metal quality" by Al Jallaf, Margaret Hyland, Barry Welch and Al Zarouni.
Two were presented by Maryam Mohamed Al Jallaf (senior manager: Process Control, Potrooms and Cell Lining), namely: *'Pushing the frontiers of anode current
density at Dubal' -- by Ali HAM Al Zarouni, Maryam Mohamed Al Jallaf and Arvind Kumar; and *'Impact of TiB2 granules on cathode wear and metal quality' -- by Maryam Mohamed Al Jallaf, Margaret Hyland, Barry Welch and Ali H A M Al Zarouni.
Welding time was 7 s, anode current
(I) of 150 mA, 180 mA, 200 mA, 240 mA, 260 mA, 300 mA changed with a constant anode voltage of 2700 V.
In correspondence with this the anode current
IA may be presented in the form of two summands: [I.sub.A] = = [I.sub.p] + [I.sub.ch], where [I.sub.sp], [I.sub.ch] are the components of the anode current
, which act on the specimen and walls of the vacuum chamber, respectively.
Other features include: a programmable xy-stage with 220 mm travel and a position accuracy of 0.3 [micro]m; an x-ray tube with voltage up to 50 kV and an anode current
of up to 0.8 mA; and a video microscope with 236X magnification.
