Purpose – Two effects simultaneously shape the future soybean meal (SBM) demand in China: the income effect on meat consumption and the transition effect due to commercial feed usage in animal production. The income effect has been studied intensively in previous research and results in...

A two dimensional, across the channel, isothermal, two-phase flow model for proton exchange membrane fuel cells (PEMFCs) is developed to investigate the interaction of dry Nafion® ionomer volume fraction (LMdry) and cathode relative humidity (RHc) in PEMFCs. The agglomerate model is used to...

A two dimensional steady state and isothermal model of a proton exchange membrane fuel cell is presented. This model is applied to a fuel cell with a counter-flow mode of hydrogen and air along parallel flow channels. In the flow channel and porous media, reactant flow is modelled using the...

A two dimensional, across the channel, steady-state model for a proton exchange membrane fuel cell (PEMFC) is presented in which the non-isothermal model for temperature distribution, the two-phase flow model for liquid water transport and the agglomerate model for oxygen reduction reaction are...
