Team:Harvard/Dailybook/Week6/Widgetry

=Goals for this week=
 * Finish building remainder of chambers to bring us up to a total of 9 working fuel cells
 * Configure Kiethley/LabVIEW to support measurement from 9 fuel cells
 * Run test with 9 identical wt chambers to test for reproducibility of results
 * Use argon instead of nitrogen on anode side

=First Nine-chamber Test=
 * Clean and re-build fuel cells in preparation for experiment
 * Reused cathodes, but replaced Nafion membrane and anode
 * Placed built fuel cells under UV light to prevent contamination



Variance Test with Shaking

What we did:

-Tested how much variance existed among chambers by running 9 parallel chambers with wt Shewie

-Switched nitrogen gas with argon gas on the anode side

-Shook chamber 1 manually to see the effect of shaking on current production

Results:

-Current production range was between 50-75 microAmps

-Red line (wt w/ shaking) went up to 500 microAmps when shaking vigorously


 * -Shows that shaking directly affects current production


 * -Therefore, amount of gas bubbling directly affects current production

- Possible to use this as direct test for computer interface
