Another way to harvest the energy is to carry out the conversion of the h2 (g) to h2o (l) in a fuel cell that generates electricity. if the fuel cell is used to provide 1 milliwatt (mw) of power for a small light, and the limiting reactant in the cell is 20 g of h2, calculate the maximum length of time (seconds) the light can operate at 25°c. notes: the reaction stops when the limiting reactant is used up. other reactants are by definition excess reactants, which means that some amount of them will be left over when the reaction stops. also, only the gibbs free energy is available to be converted into electricity!
