(j) application of principles of electrode potentials to modern storage cells
{Details of storage cells and required equations will be provided. Relevant electrode potentials and other data will be supplied.}
{Benefits of electrochemical cells counteracted by risks from toxicity and fire from Li-based cells}
(k) explanation that a fuel cell uses the energy from the reaction of a fuel with oxygen to create a voltage and the changes that take place at each electrode.
{Recall of fuel cells and equations will not be required. Relevant electrode potentials and other data will be supplied.}
