"Micro-structured flow channels on bipolar plates constructed of metal films mean that the usual diffusion layer can be avoided, so that we achieve a very flat construction in comparison to conventional cells."

  Electrolytes

The "electrolyte" is that part of any fuel cell which separates the positively and negatively charged ions (e.g. protons and electrons in a PEMFC) which are formed by catalysis of the fuel (hydrogen) at the anode, allowing the protons but not the electrons to pass through to the cathode, and forcing the electrons to reach the cathode through an external circuit where the electrons can do work as electricity. The electrolyte used is what gives a particular type of fuel cell its name: alkaline, molten carbonate, phosphoric acis, PEM, etc.
