This work addresses issues of long-term durability of hydrogen鈥揳ir proton exchange membrane fuel cells (PEMFCs) under cyclic current loading conditions, simulating the real road driving conditions for automoti
(tap and waste water), food and beverage filtration, pharmaceutical and electric processes, blood filtration, tea bags and coffee and juice filters, cooking oil filters and oil/fuel filtersfor automotives. Nonwovens have been successfully used in the industry as membrane support for micro-filtration...
1)RESULTS AND DISCUSSIONThe “silyl method” has been successfully applied for the preparation of PESs by nucleophilic displace-ment reaction in the melt from DFDPhS and trimethylsilylether derivatives of PhHQ and DFDPhS. Thegeneral chemical structure of the synthesized PESs is given in Fig. 1.I...
As diesel engines are widespread in transportation, it is of crucial importance to significantly diminish the concentration of the pollutants and greenhouse gas emissions in the exhaust gas flows [8]. 1.2. Overview of Hydrogen Utilization in Automotives According to the Paris Agreement, signed by ...
This has led to its widespread use, such as in stationary power stations, consumer devices, and automotives. However, the reliability and durability of PEM fuel cells are still two major barriers to its further commercialization. To address these issues, a set of studies have been devoted to ...
