QUESTIONS 1. a) Determine the thermodynamic reversible cell potential of an air/direct methanol fuel cell (DMFC) operating at STP (298K,1atm) and at a methanol concentration of 1M. b) Show the dependence of the reversible cell potential on temperature and methanol concentration for the following temperature and concentration range: 30,40 and 50C and 2M,3M,5M methanol by plotting VvsT and V vs concentration plot. Anode: CH3OH+H2O=CO2+6H++6e Cathode: 6H++6e+3/2O2=3H2O Hint: Use the thermodynamic table uploaded to the MS Teams page of the course to find enthalpy and entropy values of compounds at 298K and 1 atm and do the calculation based on these values. For the temperature and concentration dependence of the reversible cell potential, please refer to the Nernst Eqn that we derived in the class. 2. An air/methanol fuel cell including 15 cells with a surface area of 100cm2 operates at 1A/cm2 and 0.3V at STP. Methanol and air are supplied to the fuel cell at 0.003 and 0.03mol/s, respectively. Calculate (a) the output mass flux (mol/s) of methanol ( vMeOH, out), air (vair, out), water ( vH2O, out), and carbon dioxide (vCO2, out); (b) the stoichiometric factors for methanol ( MeOH) and air ( air); and (c) the heat generation 3. Please explain the current technological challenges of direct methanol fuel cells and strategies offered to overcome these challenges (Max 400 words). Please also include the references that you find during the literature search for supporting your arguments and add to the end of your
