The open circuit voltage of a hydrogen-oxygen fuel cell operating at RTP is 0.96 V and its internal resistance is 1.2 m Ohm. The activation voltage drop is given by

V_act =0.031 + 0.015 In I

where I is in amperes. From thermodynamic data, the reversible voltage, V_revis known to be 1.20 V. Two hundred of the above cells are connected in series forming a battery that feeds a resistive load rated at 2.5 kW at 100 V. Determine

a) the actual load voltage [V], and

b) the thermal energy [W] generated internally.
