Stainless steel mesh (SSM) with four opening sizes (20–80M) were investigated as matrixes of activated carbon air–cathodes in microbial fuel cells (MFCs). The highest power density of 2151±109mWm −2 (at 5.54±0.14Am −2 ) was obtained using 40M, with a value 45% higher than 1485±18mWm −2 of 80M. The trend of linear sweep voltammetries were in accordant with power output over...
This study provides technological change, factor demand and inter-factor substitutability measures for China electricity industry. We use individual fuel price data and translog factor cost function approach to estimate total factor cost functions and fuel share equations. The implied price and Morishima substitution elasticities for inter-factor are obtained. By estimating the substitution between...
