Difference between ideal fuel cell and actual fuel cell is given below: Actual fuel cell Ideal fuel cell In actual fuel cell the transport of oxidizer electrolyte fuel and product from electrode. Proper proportion and maintained. And Surface is not proper proportion and complex. System is simple. Homogeneous reaction turbine place for three face of oxidizer a liquid fuel electrode and solid electrode.  No homogeneous reaction takes place. The diffusion process at the electrode surface is quiet complex. In ideal fuel cell the diffusion process at the electrode surface is quiet simple. Too much liquid or gas enters the electrolyte and reduce the surface. No liquid gas enters. In an actual fuel cell activation energy reduces the work of cell. In ideal fuel cell there have no activation energy. In an act...

Difference between fuel cell and battery is given bellow:                           Battery                                   Fuel Cell 1)     Battery is a close system. Fuel cell is open system. 2)     Chemical Changes occurs There is no change in chemical composition of electrolyte. 3)     Fuel supply intermittent. Fuel supply continuous. 4)     No isothermal reaction inside. Isothermal reaction inside. 5)     Supply power for definite length of time. Fuel cell supply power for indefinite length of time. ...

Fuel Cell:  Fuel cell is a steady flow device in which a fuel and an oxidizer are combined chemically in an isothermal reaction to produce electrical work. The fuel and oxidizer do not come into contact directly with each other. Operation of a fuel cell or construction:  Operation of a fuel cell completely by two reaction and which is divided by two that occurs on separate electron. One reaction is occurring on the surface of one electrode and ionizes   the fuel and released electrons into an external circuits. Other reaction takes place on the surface of the second electrode, a reaction occurs that accept electron from external circuit and ionize the oxidizations.
