Hi All,
So the task is to calculate amongst other things, the Storage Density and the Energy Density of the Ethanol fuell cell.
I have calculated the Storage Density: Capacity/Weight of EtOH = 2.5 x 10^7 C Kg^-1
Which I think is ok. Now, I have been told that to calculate the Energy Density we use: Voltage x Storage density. So i get the answer 6.3 x 10^7 V C kg^-1...but the units they want is watt hours per kilogram (W h kg-1)- and here lies the problem. Can anyone tell me how to convert???
Thanks All
