The research activity aims to develop novel catalyst layers for proton exchange membranes (PEMs) in water electrolysis. The objective is to enhance the efficiency and durability of PEM electrolyzers, which are key components in hydrogen production systems.
The expected outcome of this research is the development of advanced catalyst layers that exhibit improved electrochemical performance and stability. By designing catalyst materials with high activity, selectivity, and durability, researchers aim to enhance the efficiency of the electrolysis process, reduce the energy consumption, and extend the lifespan of the PEM electrolyzers.
These novel catalyst layers are expected to enable more efficient and cost-effective hydrogen production through water electrolysis. By optimizing the catalyst composition, structure, and interaction with the membranes, the research activity seeks to overcome the limitations of existing catalyst layers and contribute to the advancement of sustainable hydrogen production technologies.
In the production process of novel catalyst layers for proton exchange membranes (PEMs) in water electrolysis, various techniques are employed to achieve optimal morphology and composition. These techniques include deposition methods, such as physical vapor deposition (PVD) or electrochemical deposition (ECD), and synthesis methods like sol-gel or wet chemical methods.
The morphology of the catalyst layer plays a crucial role in determining its catalytic activity and stability. The student will focus on controlling factors such as particle size, shape, and distribution within the catalyst layer. These parameters directly influence the accessibility of reactants to the active sites, mass transport properties, and overall electrochemical performance.
In addition to morphology, the choice of support material is critical for the catalyst layer’ performance. Support materials provide structural stability and serve as a platform for catalyst deposition. Common support materials include metal oxides, including titanium dioxide or cerium oxide and novel material as silicon carbide, and nitrides (vanadium, et.). The selection of the support material depends on factors such as its electrical conductivity, chemical compatibility with the catalyst and electrolyte (as pH and polarization), and durability under the operating conditions of the PEM electrolyzer.
By carefully controlling the productive process and optimizing the morphology and support material, the student aim to develop catalyst layers that exhibit high catalytic activity, stability, and efficient charge transfer.
The outcome of this research has the potential to significantly impact the field of water electrolysis by providing a pathway for the commercialization of PEM electrolyzers with enhanced performance and longevity. The development of novel catalyst layers can accelerate the adoption of hydrogen as a clean energy carrier, facilitating the transition to a more sustainable and
