Which types of electrolyzers that can also be used as fuel cells?7 answersThe exploration of electrolyzers that can double as fuel cells is a significant area of interest in the quest for efficient, sustainable energy conversion and storage technologies. Among the various types of electrolyzers, Solid Oxide Electrolyzers (SOE) and High-Temperature Electrolyzers (HTE), also known as Solid-Oxide Electrolyzers (SOE), stand out for their reversibility, allowing them to function both as electrolyzers and fuel cells. This dual functionality is attributed to their operation principle, where, in electrolyzer mode, they electrolyze steam or carbon dioxide to produce hydrogen, syngas, or methane, and in fuel cell mode, they generate electricity and heat from fuels.
Solid Oxide Cells (SOC), including both SOE and High-Temperature Electrolyzers, are particularly noted for their ability to operate in a reversible mode as Reversible Solid-Oxide Cells (rSOC). This reversibility means that with a single unit, one can switch between generating electricity from fuels in the Solid-Oxide Fuel Cell (SOFC) mode and producing valuable fuels from electricity and steam or carbon dioxide in the Solid-Oxide Electrolysis Cell (SOEC) mode.
Anion Exchange Membrane (AEM) technologies, encompassing AEM Water Electrolyzers (AEMWEs) and AEM Fuel Cells (AEMFCs), also present a unique case. While primarily discussed in the context of their respective roles in hydrogen production and utilization, the underlying technology based on ion exchange and electrochemical conversion processes suggests a potential for reversibility, although direct references to their use in both roles simultaneously are less explicit.
Protonic Ceramic Fuel Cells and Electrolysers (PCFC and PCEC) are another category where the material and mechanism for proton incorporation and conduction indicate a potential for dual functionality. These devices utilize ceramic materials that facilitate proton conduction, a property that can be leveraged in both fuel cell and electrolyzer modes, although the focus is often on their distinct applications.
In summary, while SOE/HTE (including rSOC) technologies are explicitly recognized for their reversible operation as both electrolyzers and fuel cells, AEM technologies and Protonic Ceramic systems also possess inherent properties that suggest a potential for dual use, albeit with a need for further exploration and clarification in the latter cases.
What are the options of catalysts for Hydrogen evolution reation on the cathode of PEM electrolysers?5 answersThe options for catalysts for the Hydrogen Evolution Reaction (HER) on the cathode of Proton Exchange Membrane (PEM) electrolyzers include various materials such as platinum group metal (PGM)-free catalysts, Mo-based nanomaterials like 1T′-MoS2, Co-MoS2, and β-Mo2C, Pd-based architectures, and PGM-free transition metal oxides derived from metal-organic frameworks. These catalysts have shown promising performance in driving the HER with low overpotentials, high efficiency, and excellent stability under acidic conditions. The development of these catalysts aims to reduce the dependency on expensive noble metals like platinum, enhance the efficiency of hydrogen production, and improve the overall cost-effectiveness of PEM electrolysis for green hydrogen generation.
What are the use of nanoparticles in electrochemistry or in catalysis technology?4 answersNanoparticles play a crucial role in electrochemistry and catalysis technology due to their unique properties. Metal nanoparticle-based electrocatalysts are extensively utilized in electronic devices for various electrochemical reactions like oxygen reduction, alcohol oxidation, and CO2 reduction, essential for clean energy systems. Metal-organic framework (MOF) nanoparticles exhibit exceptional catalytic abilities, aiding in diverse reactions such as organic, molecular, photocatalysis, and electrocatalysis, addressing environmental and energy challenges. Additionally, the use of tobacco mosaic virus coat protein (TMVCP) as a platform for metallic nanomaterial synthesis has shown promise in energy-related electrocatalytic reactions, offering eco-friendly and superior catalysts for reactions like electrochemical CO2 reduction and methanol oxidation. These nanoparticles, with their enhanced reactivity and versatile applications, hold significant potential in advancing catalysis technology and addressing current environmental concerns.
What is electrolysis?5 answersElectrolysis is a process that involves the use of electrical current to drive a non-spontaneous chemical reaction. It typically takes place in an electrolysis cell, which consists of two electrodes - an anode and a cathode - immersed in an electrolyte solution. When an electric current is passed through the electrolyte, positive ions migrate towards the cathode, where reduction reactions occur, while negative ions migrate towards the anode, where oxidation reactions occur. This results in the separation of the components of the electrolyte into their constituent elements or compounds. Electrolysis has various applications, including the production of hydrogen and oxygen from water, and the splitting of water into hydrogen and oxygen using a pulse width modulated voltage. It is also used in electrochemical cells for energy storage and conversion.
What are the different types of electrolytes used in electrochemical cells?2 answersDifferent types of electrolytes used in electrochemical cells include: an aqueous electrolyte impregnated in a hydrophilic polymer matrix, an ionic liquid with a quaternary cation and a boron cluster anion, sulfuric acid and potassium hydroxide separated by a proton exchange membrane, ceramic electrolyte layers made of Li1+zAlzM2-z(PO4)3, and thin polymer layers formed by initiated chemical vapor deposition (iCVD).
What are the advantages of using electrochemistry in the production of chemicals?1 answersElectrochemistry offers several advantages in the production of chemicals. It provides a mild, green, and atom-efficient route to synthesizing interesting and useful molecules, avoiding the use of harsh chemical oxidizing and reducing agents typically used in traditional methods. Electrochemical techniques are versatile and powerful for the assembly of heterocyclic structures, offering a wide range of possibilities for the construction of various compounds. Additionally, electrochemical conversion processes can be performed in aqueous solutions at ambient temperature, following the principles of green chemistry. Electrochemistry also allows for the cleavage and coupling of C-C bonds without excessive heating, offering a sustainable alternative to traditional methods. Furthermore, electrochemical energy storage and conversion technologies, such as batteries, electrolysers, and fuel cells, provide a promising solution for broad-based energy storage applications and the conversion of N2, H2O, and CO2 into valuable energy carriers and chemical feedstock.
