Fuel cells can be powered by the reaction between formic acid and oxygen as following As formic acid and oxygen react together inside the fuel cell, it produced both electrical power and heat. While there is no shaft work produced by the fuel cells, this electrical power produced by the fuel cells can be considered as the shaft work term when you perform the energy balance. A fuel cell is being supplied with 100. liters per minute of pure formic...
