Winter 2012 Q7A&B

I am confused about Winter 2012 Q7A&B and Winter 2013 Q7 because the overall cell potential is negative and I thought that you always want a positive cell potential? Is there a special rule I am unaware of?

You can have a negative cell potential, it is just preferred to have a positive. With a negative you would need an external voltage.
