verall reaction: N2H4+O2N2+2H2O(E=1.56V igure 1: Schematic of the hydrazine fuel cell equipped with an anion exchange membrane 1]. RHE: reference hydrogen electrode erform the following: A) Calculate the theoretical (thermodynamic) specific energy of the hydrazine fuel cell expressed in [kWh / kg_hydrazine] and compare it with the H2 fuel cell. Note: if you require thermodynamic data use Handbooks available on-line through UBC Library. B) If the fuel cell is operated with a superficial current density of 500mA/cm2 and the electrode geometric area is 250cm2, calculate the following: i) extent of fuel cell reaction [mol mreaction/s], ii) the volumetric inlet flow rate [cm3/min] for the anolyte solution composed of 4M hydrazine in 4MKOH assuming the goal is to have a high hydrazine conversion at the anode of 90%, iii) the volumetric flow rate [cm3/min] of N2 gas produced at 1atm and 60C, iv) the mass of hydrazine [g ] consumed during 1 hour of continuous operation. Assume steady-state. C) Calculate the: i) air flow rate [cm3/min, at 273K and 1 atm, air 20%O2 by vol.] stoichiometrically required to sustain the anode reaction as described at question 2 , and ii) the molar flow rate of hydroxide crossing the membrane
