Process parameters for maximum power of a proton exchange membrane fuel cell

  Pressure and temperature of the cell are the effective parameters in performance of proton exchange membrane (PEM) fuel cell. In this study, a genetic algorithm is applied to determine operating conditions that result in maximum power density of a proton exchange membrane fuel cell (PEMFC). A quasi two dimensional, isothermal model is presented for PEM fuel cell and the polarization curve of the system could...

Statistical analysis and evaluation of lithofacies from wireline logs over ‘Beleema’ field, Niger Delta, Nigeria

  A statistical analysis of well-log data for the purpose of estimating and evaluating lithofacies with depth, around ‘Beleema’ field, Niger Delta, was carried out. The principal component analysis (PCA) technique and the bulk volume water and the grain size relationships formed the main principles of analysis. The PCA was applied to selected lithology-sensitive logs, each serving as a variable...
