ABSTRACT:  This presentation will provide an overview of recent progress and remaining technical challenges of PEM fuel cells. The important contribution of catalyst materials and catalyst layer towards wide-spread commercialization of fuel cells will be highlighted. The advantage and possible limitations of various types of catalysts, such as Pt alloys (de-alloys), core-shell catalysts and shape-controlled nanocrystal catalysts will be assessed.

ABSTRACT:  Mathematical programming methods have been widely adopted for process design and operation, as they provide systematic means to find optimal or feasible design/operation decisions that may not be easily seen from qualitative or simple quantitative analysis. However, mathematical programming formulations of process design and operation problems are usually nonconvex, implying that an optimal, or even a feasible solution, is difficult to obtain.

ABSTRACT:  In order to reduce carbon emissions and construct sustainable society, it is very important to construct sustainable biorefineries, which produce biofuel/biochemical from biomass. Consolidated bioprocessing (CBP), which integrates enzyme production, saccharification and fermentation into a single process, is a promising strategy for effective bioproduction.
