1 ME 417 Design of Alternative Energy Systems Fuel Cell Problems 1. Determine the ideal voltage, current, and required mass flow rate of hydrogen for an ideal air/hydrogen fuel cell operating at 101 kPa and 350 K that is producing 25 kW. 2. Determine the ideal voltage, current, and required mass flow rate of ethanol (C 2 H 6 O) for an ideal air/ethanol–water fuel cell operating at 101 kPa and 280 K that is producing 500 kW. You may take the c

Unformatted text preview: P of ethanol to be 2.77 kJ/(kg ⋅ K). 3. Determine the ideal voltage, current, number of stacks required, and required mass flow rate of isopropanol (C 3 H 7 OH) for an ideal air/isopropanol –water fuel cell operating at 101 kPa and 298 K that is producing 50 kW. You may take the following properties for liquid isopropanol. c P = 2.35 kJ/(kgK) kmole / kJ 000 , 316 h f-= ) K kmole /( kJ 6 . 194 ) K 298 at ( s o ⋅ =...
