A"direct methanol fuel cell" uses chemical reactions involving a weak methanol solution and oxygen gas in order to generate an electric current. the overall reaction can be described as the actual processes occurring at the anode and cathode are, respectively ch, oh + h2o → 6h+ + 6e-+ co2. 0, g311). 2 (a) calculate the maximum possible work that the fuel cell could produce from 1 mole of methanol. what voltage can the fuel cell maintain? (b) under reversible operation, would the fuel cell tend to get warmer or cooler? calculate the heat (per mole of methanol) that must enter or leave in order to maintain the fuel cell at constant temperature data for methanol ch ohl): ah -238.66 kj/mole arg -166.27 kj/mole s 126.8 j/mole k
