Cohesive zone modelling of hydrogen induced cracking on the interface of clad steel pipes
(Peer reviewed; Journal article, 2017)A coupled finite element hydrogen diffusion and cohesive zone modelling approach has been applied to simulate hydrogen induced fracture initiation in a hot rolled bonded clad steel pipe. The results are compared to ... -
A coupled diffusion and cohesive zone modelling approach for numerically assessing hydrogen embrittlement of steel structures
(Peer reviewed; Journal article, 2017)Simulation of hydrogen embrittlement requires a coupled approach; on one side, the models describing hydrogen transport must account for local mechanical fields, while on the other side, the effect of hydrogen on the ... -
Development of novel metal-supported proton ceramic electrolyser cell with thin film BZY15–Ni electrode and BZY15 electrolyte
(Peer reviewed; Journal article, 2017)Metal supports for planar MS-PCEC were manufactured using tape-casting of low-cost ferritic stainless steel. A coating protecting the metal support against oxidation was applied by vacuum infiltration and a buffer layer ... -
Economic assessment of membrane-assisted autothermal reforming for cost effective hydrogen production with CO 2 capture
(Peer reviewed; Journal article, 2019)A recent techno-economic study (Spallina et al., Energy Conversion and Management 120: p. 257–273) showed that the membrane assisted chemical looping reforming (MA-CLR) technology can produce H2 with integrated CO2 capture ... -
Formation of hydrogen bubbles in Pd-Ag membranes during H2 permeation
(Peer reviewed; Journal article, 2019)Palladium membranes used for hydrogen separation seemingly develop cavities filled with hydrogen, i.e. hydrogen bubbles, along the grain boundaries. These bubbles may represent initial stages of pinhole formation that lead ... -
Gas Switching Reforming for syngas production with iron-based oxygen carrier-the performance under pressurized conditions
(Peer reviewed; Journal article, 2019)A four-stage Gas Switching Reforming for syngas production with integrated CO2 capture using an iron-based oxygen carrier was investigated in this study. The oxygen carrier was first reduced using dry methane, where high ... -
Hydrogen from wet air and sunlight in a tandem photoelectrochemical cell
(Peer reviewed; Journal article, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ... -
Hydrogen quality sampling at the hydrogen refuelling station - lessons learnt on sampling at the production and at the nozzle
(Peer reviewed; Journal article, 2019)Fuel cell electric vehicles and hydrogen refuelling infrastructure are developing quickly in Europe, the USA and Asia. Hydrogen quality for transport applications requires compliance with ISO 14687-2: 2012 and EN 17124:2018 ... -
Hydrogen-enhanced fatigue crack growth behaviors in a ferritic Fe-3wt%Si steel studied by fractography and dislocation structure analysis
(Peer reviewed; Journal article, 2019)The effect of hydrogen (H) on the fatigue behavior is of significant importance for metallic structures. In this study, the hydrogen-enhanced fatigue crack growth rate (FCGR) tests on in-situ electrochemically H-charged ... -
Measuring the thermal conductivity of membrane and porous transport layer in proton and anion exchange membrane water electrolyzers for temperature distribution modeling
(Peer reviewed; Journal article, 2019)Water electrolyzers that use a membrane electrolyte between the electrodes are a promising technology towards mass production of renewable hydrogen. High power setups produce a lot of heat which has to be transported through ... -
Probability of occurrence of ISO 14687-2 contaminants in hydrogen: Principles and examples from steam methane reforming and electrolysis (water and chlor-alkali) production processes model
(Peer reviewed; Journal article, 2018)According to European Directive 2014/94/EU, hydrogen providers have the responsibility to prove that their hydrogen is of suitable quality for fuel cell vehicles. Contaminants may originate from hydrogen production, ... -
Soldering a gas diffusion layer to a stainless steel bipolar plate using metallic tin
(Peer reviewed; Journal article, 2018)A novel investigation to decrease the interfacial contact resistance of stainless steel bipolar plates was performed. A thin layer of Sn was electrodeposited onto a bipolar plate and subsequently joined with a gas diffusion ... -
Stability investigation of micro-configured Pd-Ag membrane modules - Effect of operating temperature and pressure
(Peer reviewed; Journal article, 2015)The long-term stability over a period of up to 50 days has been reported for various designs of microstructured Pd77Ag23 membrane modules for H2 production and purification. Even though microchannels provide sufficient ...
