A H, fuel cell generates 4A current output, cell reaction: H,(g) + ½O,(g) → H,O(g) (1) What is the mass flow rate of H, (moles s1) consumed (needed)? (2) What is the mass flow rate ofO, consumed? (3) If O, is from air, and the composition of air is: O, 21% and N, 79%, what is the molar rate of air needed? (4) How much water (in g) is generated on the cathode per hour?
