Ilooklikemyavatar..exactly asked: Is it possible to get a giant mobile wind turbine on wheels that can be placed in hurricanes in order to collect large amounts of energy? For example, how about a very rugged turbine(like propeller you would use for planes going 500 MPH) and a energy storage device that converts aluminum oxide to [...]

A hydrogen fuel cell stack(terminal voltage 9V) has an internal resistance of 1 Ohms. It is connected to hydrogen and oxygen reservoirs. It is being charged using a battery of 11 V terminal voltage and 1 Ohms internal resistance. a. How many moles Hydrogen are produced per second? How long does one have to charge to store 10kJ in chemical energy (the energy content of hydrogen is 242 kJ/mol of Hydrogen)? b. What is the conversion efficiency from chemical energy in the battery into chemical energy of hydrogen? c. Now the fuel cell is used as a source to operate a device w/ 5 Ohms resistance. What is the power consumed by the device? What is the conversion efficiency from Hydrogen-chemical-energy into energy consumed by the device?
