For part b, I don't want to seem stupid, but are you sure that's the method for fuel cells? Because it seems like you're still talking about combustion engines.
So the energy release is -702.36 kJ and 20% of that would be -140.47 kJ which would be the work done?
Also, I haven't really a clue how to start b even after the hint you gave me... I don't know how to find the combustion temp of methanol. I'm sorry for all the questions, but I really am lost...
