The number of moles of H 2 transported per second is given by J /2 F . In essence, the present proton conductor tube constitutes a precise, current-controllable device, with a response time of a few seconds only, that delivers ultrahigh-purity hydrogen to a vacuum system....
Proton transfer refers to the movement of protons (H+) in biological processes such as photosynthesis and respiration, as well as in fuel cells and sensors. It is closely related to hydrogen bonding and can occur along hydrogen-bonded water chains or peptide assemblies, enabling proton conduction...
Protons and neutrons have been shown to be made up of smaller particles and are classified as baryons—particles composed of three elementary units of matter known as quarks. Protons from ionized hydrogen are given high velocities in particle accelerators and are commonly used as projectiles to ...
Top, right panel: Free energy for the binding of aniline as a function of the distance (dNi–N) between the Ni center and the N atom of aniline, and as a function of the fractional number (nNH) of hydrogen atoms around the N atom of aniline (coordination number) obtained from hybrid ...
However, the proton transport number decreased to 0.52 because the electron-hole current increased along with protonic current according to the defect equilibrium reaction occurring under a wet atmosphere containing oxygen. During operation, the hydrogen evolution rate fluctuates over time by at least ...
Combining experimental results and first-principles calculations, we attribute these intriguing properties to the high proton concentration and the well-ordered oxygen vacancy channels granted by the hydrogen-intercalated brownmillerite crystalline structure. Our results open the possibility of using solid ...
In article number 1903871 , Feng‐Yuan Zhang and co‐workers report an innovative electrode design which features mesoporous nanolayer catalysts that significantly augment the accessible electrochemical reaction sites and catalyst utilization for water splitting and hydrogen production. The multilayer‐electrode...
2b. The number of hydrogen atoms (MH) stored in Bi-Hx/NF was estimated to be 13.52 μmol based on the amounts of the produced H2 (\({\mathrm{M}}_{{\mathrm{H}}_{2}}\)) and O2 (\({\mathrm{M}}_{{\mathrm{O}}_{2}}\)) in Fig. 2c (MH = 4\({\mathrm{M}...
A regenerative fuel cell system is provided having at least one hydrogen storage container fluidly coupled to at least one hydrogen generator and at least one power generator. Each
It is shown that structurally symmetrical, easily polarizable SH S - - S HS, N + H N N H + N, and OH O - - O HO hydrogen bonds are formed between the side chains. The different wave number distributions of the ir continua caused by these hydrogen bonds show that the barrier in ...
