Again, science project help.
dude you need more information in the question- fuel cells in cars? - in that case they are liquids of hydrogen and oxygen that are combusted internally in an engine, the technology is not finished yet though, And pretend you ment fuel cell literally moving a turbine, in that case fuel may be burnt to heat water, where the steam would turn a turbine to produce electricity.
No, fuel cell combine (usually) hydrogen and oxygen together in a process that is the reverse of water electrolysis. A fuel cell releases electricity; there is no need for a heat transfer fluid or a turbine.
usually no. Fuel cells generate electricity directly. You could use the electric output from a fuel cell and use that to drive an electric motor, which drives a turbine, but for what purpose.
