PEM electrolysis for hydrogen production: principles and applications
(CRC Press, 2015)
An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been ...
Synthesis of a hybrid MIL-101(Cr)/ZTC composite for hydrogen storage applications
Metal–organic frameworks (MOFs) hybrid composites have recently attracted considerable attention in hydrogen storage applications. In this study a hybrid composite of zeolite templated carbon (ZTC) and Cr-based MOF (MIL-101) ...
Gas crossover mitigation in PEM water electrolysis: hydrogen cross-over benchmark study of 3M's Ir-NSTF based electrolysis catalyst-coated membranes
In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated ...
Characterisation tools development for PEM electrolysers
Electrochemical impedance spectroscopy (EIS), current interrupt (CI) and current mapping (CM) were investigated as in-situ characterisation tools for PEM electrolysers. A 25 cm2 cell with titanium anode and carbon cathode ...
Theoretical limit of reversible hydrogen storage capacity for pristine and oxygen-doped boron nitride
To achieve higher hydrogen storage capacity than that of compressed gas vessels, new advanced materials must be developed. Among the most promising are two-dimensional layered nanomaterials, such as graphene and boron ...
Insights on hydrogen evolution reaction in transition metal doped monolayer TcS2 from density functional theory calculations
The catalytic activity for hydrogen evolution reaction (HER) in monolayer TcS2 has been investigated using vander Waals corrected density functional theory. Also, the influence of transition metal dopants (Fe, Co, Ni, Pd ...
PBI-blended membrane evaluated in high temperature SO2 electrolyzer
It has been shown that hydrogen can be produced efficiently within the membrane based Hybrid Sulfur (HyS) process, where SO2 is electrochemically oxidized in the presence of H2O to produce H2 and H2SO4. In earlier studies, ...
Modulated synthesis of zirconium-metal organic framework (Zr-MOF) for hydrogen storage applications
A modulated synthesis of Zr-metal organic framework (Zr-MOF) with improved ease of handling and decreased reaction time is reported to yield highly crystalline Zr-MOF with well-defined octahedral shaped crystals for practical ...
