Nền kinh tế hydrogen: Con đường còn xa?

tailieu.vn

Một hướng nghiên cứu khoa học để giải quyết các khó khăn trên là đi tìm một cách {tồn trữ hydrogen bằng hoá học} (chemical hydrogen storage). Nói nôm na là tìm một hợp chất hoá học có chứa H2, và chất này có thể tạo ra H2 bằng một phản ứng hoá học đơn giản, và sau khi được tạo ra, H2 được chuyển trực tiếp vào pin nhiệt điện để tạo ra năng lượng. Hợp chất hoá học có thể ở thể lỏng hay thể rắn, phải có nồng độ H2 cao, dễ bảo quản, không nguy hiểm khi tồn trữ trong xe, chuyên chở hay phân phối..

Accelerated FeIII/FeII redox cycle of Fenton reaction system using Pd/NH2-MIL-101(Cr) and hydrogen

tailieu.vn

Key words: Fenton reaction, accelerated reduction of Fe III , hydrogen, palladium, NH 2 -MIL-101(Cr). Although the MIL-101(Cr) will be gradually damaged during the reaction process [44,45]. The NH 2 -MIL-101(Cr), which could be stable in water and has acted as a novel material for hydrogen storage, applications in catalysis and the carrier for Pd was chosen to be used in this paper. The reaction mechanism of this novel MHACF-NH 2 -MIL-101(Cr) system is depicted in Scheme 1..

Aviation: Fuel Cells

tailieu.vn

Reactant storage is one of the primary design chal- lenges for fuel cell aircraft of all types, but especially for those that consume hydrogen. Although all fuel cell aircraft that have in- corporated chemical hydrogen storage media have used a centralized hydrogen storage unit, this is not necessarily an intrinsic feature of chemical hydrogen storage.

Light Traction: Fuel Cells

tailieu.vn

Due to the low hydrogen storage capacity and the lack of hydrogen infrastructure, FCs using direct-feed liquid fuels are very attractive for light traction applications owing to their high volumetric energy density and ease of storage and transportation. The most widely investigated system is the direct methanol fuel cell (DMFC).. Methanol stored in a fuel tank is mixed with water and the resulting mixture is sent to an FC stack.
