Long description of figure

The electrochemical cell pictured on the left identifies the fiber electrode, the auxiliary electrode, and the bromide ions in solution. To the right, the same cell is shown with the effects of applying a potential. The bromide ions are being intercalated into the fiber electrode, and hydrogen gas is being generated at the auxiliary electrode. The chemical equations for the half reactions occurring at each electrode are also shown: 7nC + nBr^- --> C_7nBr + e^- at the bottom of the fiber electrode and 2H⁺ + 2e^- --> H₂ at the bottom of the auxilliary electrode.
