The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. This paper presents a corrosion sensor for steel based on an iron film-coated optical fiber polarizer. The polarizer is fabricated by sputtering a Fe-C film on a side-polished single mode fiber. The new fabricated polarizer shows highly birefringence, indicated by the difference of the transmission between...
A dynamic model for the thermal system of a PEM fuel cell stack is proposed in this paper. It is based on the theory of heat transfer and mass transfer. And it is intended to be used for system analysis and control. The model can not only predict the variables and states in steady case, it can also describe their transient process when the output current varies with load. Besides, it can give insight...
Along with rapid economic development in China, the energy consumption and pollutants emission are increasing rapidly. It has caused great pressure to resource and environment. How to improve energy productivity in a more cost-effective manner and reduce atmospheric pollutants emission is a big problem at present. Based on Chinese energy consumption and atmospheric pollutants emission between 1990...
