Should the anode potential be increased or decreased to generate current? I am taking a course on fuel cells and we were talking about the activation energy needed to start a chemical reaction.

I would think that the answer to this question is that the anode potential should be increased to generate current so less energy is needed to begin the reaction. 

Is this right? Or am I way off track.
Use Nernst equation. If you increase anode potential, the cell potential becomes more negative, thus decreasing Gibb's energy. This makes the reaction less feasible.
