1. A direct methanol fuel cell generates 1000A at 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 molar flux (mol/s) of methanol, air (b) the stoichiometric ratio for methanol ( SMeOH) and air ( Sair); and 2. You are provided with a fuel cell that is designed to operate at i=3A/cm2 and P=1.5 W/cm2. How much fuel cell active area (in cm2 ) is required to deliver 2kW of electrical power? (a) 296.3cm2 (b) 1333.3cm2 (c) 444.4cm2 (d) 666.6cm2
