    Fuel cell/rechargeable cell graphs
    I remember seeing a graph of a fuel cell and rechargeable cell as the charge is used up but I can't find them. Does anyone know how to draw the graphs?

    The EMF/time graph for the fuel cell is just a straight, horizontal line. For the battery it starts off as a horizontal line but then curves downwards as the reactants are used up.

    I think the graphs you're looking for are in the AQA CHEM5 June 2011 paper.
