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 automotives. The same type of membrane鈥揺lectrode assembly (MEA) was also aged under constant ...
(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...
As such, any increase in the cost of oil sparks even more interest in gasoline alternatives. Things like electric cars and hydrogen fuel cells are being talked about as feasible alternatives to oil. But, not lost in the mix are the biofuels, fuels made from biological ingredients instead of ...
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 ...
