The advantages of composite materials, on the one hand, can enhance the protection of iron oxide and reduce the loss of iron, on the other hand, can give full play to the synergistic effect between different materials.
In the selection of carrier materials, besides the stability of materials and the compatibility with iron, the cost factor is also very important.
Due to these materials are generally charged negatively and have large specific surface area, iron ions are easy to accumulate on the surface of clay materials or enter their internal space through ion exchange.

Modern functional metal oxide materials are based upon the use of nanostructured particles.
In recent years materials on the basis of yttrium oxide find ever-widening application.
These compounds are used in high-performance luminescence devices [1, 2], as phosphors [3–13], the reactants for synthesis of nanotubes [14], nanowires [15] and nanorods [16–17], as well as other functional materials.

Challenges in Hydrogen Fuel Cell Vehicles Commercialization Yuan Ren, Zhidan Zhong, Zhiwen Zhang School of Mechatronics Engineering, Henan University of Science and Technology Luoyang 471003, Henan Province, China,ryemailcn@163.com Keywords: Hydrogen Fuel Cell Vehicle; Proton Exchange Membrane Fuel Cells (PEMFCs); Material for Catalyst; cost; Commercialization Abstract:Current development in fuel cells and hydrogen fuel cells vehicles are first described in the paper, and then the paper gives up-to-date review of hydrogen fuel cell vehicle technological status and hydrogen infrastructure.
Then the paper analysis barriers in hydrogen fuel cell vehicle commercialization and the cost reduction challenges especially in the material for catalyst and operational condition.
Proper understanding the basic science of fuel cells working principle at the atom level is vital important for us to do.
The second is the membrane fabrication techniques and the third is the coating and plate material of bipolar plates.
For PEMFC, research efforts focused on improving technological performance in the 1980s and 1990s, and then turned towards reducing the cost of PEMFC, particularly in terms of finding a replacement material for the platinum catalyst. 3.1 Catalyst material Long-term durability of catalysts is considered as the most critical issue to commercialize the fuel cell vehicles.
