It is critical to alleviate problems of energy and air pollutants emissions in the metropolis because these areas serve as economic engines and have large and dense populations. Drivers of fossil fuel use and air pollutants emissions were analyzed in metropolis of Beijing during 1997–2010. The...

Although China has implemented many air pollution control policies, its air pollution problems remain severe with rapid economic development. The strategy of controlling single pollutant in one period and adding another in the next period (i.e., gradual control strategy) adopted in China has...

In this paper, the behavior of CO2 transmission in a micro direct methanol fuel cell (μDMFC) is investigated through both simulations and experiments. A model is built to describe the change of CO2 volume fraction in the anode channel under different operation parameters (e.g., current density,...

In this paper, the response surface methodology is applied to optimize the operating conditions of μDMFC (micro direct methanol fuel cell). Three operating parameters, the methanol flow rate, the methanol concentration and the cell temperature are considered in this study, and the ranges of...
