What is the maximum work that can be obtained from a hydrogen– oxygen fuel cell at standard conditions that produces 1.00 kg of water at 25oC? Why do we say that this is the maximum work that can be obtained? What are the advantages and disadvantages in using fuel cells rather than the corresponding combustion reactions to produce electricity?
Answer to relevant QuestionsThe overall reaction and standard cell potential at 25oC for the rechargeable nickel–cadmium alkaline battery is Cd(s) + NiO2(s) + 2H2O(l) → Ni(OH)2(s) + Cd(OH)2(s) ϐo = 1.10 V For every mole of Cd consumed in the ...In 1973 the wreckage of the Civil War ironclad USS Monitor was discovered near Cape Hatteras, North Carolina.
