What are electrocatalysts, electrochemical cells and electrolysers?
Electrocatalysts are materials that accelerate electrochemical reactions without being consumed in the process, and are essential in applications such as hydrogen production by electrolysis. Their composition and structure determine the energy efficiency of the system, which is why research into advanced catalytic materials is essential for the development of highly efficient electrolysers.
Electrochemical cells are devices that convert chemical energy into electrical energy or vice versa. They include galvanic cells (such as batteries) and electrolytic cells, used in the production of hydrogen from water. Thus, electrolysers are a specific type of electrochemical cell that allows water to be separated into hydrogen and oxygen through the use of electricity, and are a key technology for the energy transition towards cleaner sources.
At INFINITIA we are experts in electrochemical testing. Applied electrochemistry that provides innovative solutions for the optimisation of catalysts and electrolysis systems.

Benefits and advantages of these technologies
The development and optimisation of electrocatalysts, electrochemical cells and electrolysers brings great benefits to industry and society. Their application in the production of green hydrogen is crucial for reducing dependence on fossil fuels and decarbonising the energy sector.
In industry, the use of high-efficiency electrolysers allows optimising energy consumption and reducing operating costs. On the other hand, advances in catalytic materials have increased the durability and resistance of these systems, ensuring optimum performance in extreme conditions. In addition, advanced electrochemical characterisation enables the identification of improvements in energy conversion and storage processes, directly impacting sectors such as sustainable mobility, energy generation and the chemical industry.
Types of electrocatalysers, electrochemical cells and electrolysers
We work with various technologies related to applied electrochemistry, optimising materials and systems to improve the efficiency of electrochemical processes. These are the main types of electrocatalysts, electrochemical cells and electrolysers.
1. Electrocatalysts for energy conversion
Electrocatalysts are materials designed to accelerate electrochemical reactions without degrading in the process. They are essential in energy production and storage, especially in technologies based on green hydrogen and water electrolysis.
- Oxygen evolution reaction (OER) electrocatalysts: These catalysts improve the efficiency of oxygen production in processes such as water electrolysis. Materials such as transition metal oxides (IrO₂ and RuO₂) or compounds based on nickel and cobalt are the most commonly used due to their stability and performance in alkaline media.
- Electrocatalysts for the hydrogen evolution reaction (HER): Optimise hydrogen production in electrolysis systems. Noble metals such as platinum are used, although alternatives based on molybdenum and tungsten are also being investigated to reduce costs without compromising efficiency.
- Electrocatalysts for fuel cells: In applications such as hydrogen fuel cells (PEMFCs, SOFCs), catalysts are required to facilitate the electrochemical conversion of hydrogen to electricity. The use of advanced materials such as noble metal nanoparticles and doped carbon-based structures is investigated.
2. Electrochemical cells for energy storage and conversion
Electrochemical cells allow energy to be converted and stored efficiently. They are used in a variety of applications, from advanced batteries to the production of synthetic fuels.
- Galvanic cells (electrochemical cells and batteries): Generate electricity from chemical reactions. They are found in lithium-ion batteries, redox flow batteries and hydrogen fuel cells. At INFINITIA we analyse their performance and optimisation through electrochemical efficiency tests.
- Electrolytic cells (water electrolysers and industrial processes): They operate in the reverse direction to galvanic cells, using electricity to induce chemical reactions. They are used in hydrogen production, metal recovery and wastewater treatment.
3. Electrolysers for hydrogen production
Electrolysers enable the production of green hydrogen from water and renewable electricity. There are different technologies depending on the type of electrolyte used:
- Alkaline electrolysers (AEL): These are the most widely used industrial electrolysers due to their low cost and operational stability. They use potassium hydroxide (KOH) solution as electrolyte and require optimised catalytic materials to improve efficiency.
- Proton exchange membrane electrolysers (PEM): Use proton-conducting polymeric membranes to separate hydrogen and oxygen. They are more efficient than alkaline ones, but require the use of platinum and iridium-based catalysts, which increases their cost.
- Solid oxide electrolysers (SOEC): These operate at elevated temperatures and enable the conversion of water and CO₂ into hydrogen and carbon monoxide, facilitating the synthesis of synthetic fuels. They are an emerging technology with great potential for the energy industry.
Applications of electrocatalysts, electrochemical cells and electrolysers in different industries
Electrochemical technologies play a key role in many industrial sectors. Their main applications are described below.
