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...

Sulfanilamide (SM), as one representative drug of sulfonamides, was commonly used for the prevention and treatment of bacterial infectious diseases and were extremely difficult to remove. Herein, an efficient catalyst (CoS/CN) for SM degradation was constructed by CoS self-assembling on...

<Para ID="Par1">Remote sensing technology for the study of Earth and its environment has led to “Big Data” that, paradoxically, have global extent but may be spatially sparse. Furthermore, the variability in the measurement error and the latent process error may not fit conveniently into the Gaussian linear...</para>
