Abstract
Magnetic composites exhibit distinct flux properties due to gradient interfaces. The composites can be used to improve fuel cells and batteries and effect transport and separation of different chemical species. Devices utilizing the composites include an electrode and improved fuel cells and batteries. Some composites, disposed on the surface of electrodes, prevent passivation of those electrodes and enable direct reformation of liquid fuels. Methods involving these composites provide distinct ways for these composites to be utilized.
Claims16
A method of making an electrode having a surface coating of a magnetic composite, wherein the electrode resists passivation, comprising the steps of:
- providing an electrode;
- casting a casting mixture onto the surface of the electrode, said casting mixture comprising an ion exchange polymer, magnetic particles, and a solvent;
- and
- evaporating the solvent from the surface of the electrode to yield an electrode having a surface coating of the magnetic composite, wherein the resulting coated electrode resists passivation.
