Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Book Chapter Description
The theme of the present concept is to summarize a brief history of hydrogen discovery, its electrolytic synthesis and use in fuel cells for electric power generation. The current status of hydrogen production and consumption, and future of hydrogen energy economy has been reviewed. The present chapter has incorporated the fundamental physicochemical properties of hydrogen, methods of its production, and the physical, adsorption, and chemical methods of its storage and transportation. A prior attention is focused on the materials being used as promising candidates for the physical and chemical storage of hydrogen. These include metal-hydrides and -nitrides, MOFs (metal organic frameworks), zeolites, carbon-based porous materials, etc. The content of the present chapter highlights about the most important electrochemical processes that involve hydrogen and the basic features of hydrogen adsorption and dissolution in metal matrices from both the gas phase and electrolyte solutions. The processes of the gas-phase and electrochemical hydrogenation of organic compounds are compared. Special attention is paid to peculiarities of electrochemical reactions of molecular hydrogen evolution and ionization. The methods for hydrogen sensor and detection in gas media as well as the contributions of chemistry and electrochemistry of hydrogen in the concept of hydrogen generation and consumption systems are briefly surveyed.
