气体利用率 meaning in English

gas effciency

The fuel cells models are presented in chapter 3 . based on the balance conditions in fuel cells stack , the dynamic performance is analyzed . the dynamic model is developed with a set of correlation equations of voltage , fuel utilization , current density and other variables involved in the operating course , which are some partial differential equations with variable coefficients
第三章以熔融碳酸盐燃料电池为例，以数值分析的方法，根据mcfc电堆发电过程中物质与电量平衡，分析了电堆的内部动态特性，就输出电压与燃料气体利用率和电流密度等相关量建立了由一组变系数偏微分方程和积分方程描述的数学模型。
