... (vehicles) hydrogen storage, up to 700 bars are needed for commercial fuel cell vehicles. This creates extreme requirements for material strength and thus safety concerns. A new metal-organic framework 5 (MOF-5) was selected as the adsorbent for H 2 storage, as it provides promising storage capacity...

...Kriston Brooks; Maruthi Devarakonda; Scot Rassat; Jamie Holladay A fixed bed reactor was designed, modeled and simulated for hydrogen storage on-board the vehicle for PEM fuel cell applications. Ammonia borane was selected by DOE’s Hydrogen Storage Engineering Center of Excellence as the initial...

...Fang-Bor Weng; Bo-Shian Jou; Pei-Hung Chi; Ay Su; Shih Hung Chan A micro-fuel-cell stack of six cells with an active area of 2.73 cm 2 and 2.5 W output power has been designed and fabricated in-house. It can go with mini hydrogen storage and provide enough power for portable electric products...

... a continuous stream of high-pressure hydrogen (up to 10,000 psi ( gauge ) ), the need for expensive, heavy, and bulky compression and storage equipment is eliminated. The omission of such equipment is especially important in combat zones where large hydrogen storage tanks could become a target...

... in hydrogen storage techniques. Compressed hydrogen storage tanks, liquid hydrogen storage tanks, and containment systems for hydrides are examined to compare their advantages, disadvantages, and potential for onboard and stationary hydrogen storage systems. Each technique reviewed possesses specific...

... of those is methane and hydrogen storage in solid, water-based clathrate hydrates. Clathrate hydrates (CH) are nonstoichiometric, nanostructured complexes of small “guest” molecules enclosed into water cages, which typically form at relatively low temperature-high pressure. In nature, CH of natural gas...

A model able to reproduce the typical profiles of electric power...

... fuel cell (PEM). The system modularity can also satisfy higher energy requirements, and the low-pressure hydrogen storage system through metal hydrides guarantees the system safety. This is constituted by several components: a polymer membrane electrolyzer powered by renewable energy sources, which...
