Determine the theoretical open circuit voltage of h2-02 fuel cells, and determine which reactant would be the oxidizer and which would be the fuel for a galvanic reaction. detern the theoretical open circuit voltage (potential) that would be required to generate hydrogen peroxide h202, with gaseous hydrogen oxygen. [10 point 6. fuel cell considered as a combined heat and power device. a given fuel cell has a st a dc, an operating voltage of 0.55 v, and an overall resistance of 5 mq at 1.2 a/cm density calculate: a) the potential loss in volt from ohmic resistance, at this condition. b) the total electrical work produced in 4 h. c) the rate of ohmic heat dissipation from the cell in watt.
