Накратко на български

Метално-органичните рамки (MOF) се изследват като нови материали за мембрани в горивни клетки, като се използват например функционализирани карбоксилатни връзки. Те предлагат екологична алтернатива на скъпите и устойчиви на разграждане флуорни полимери, като помагат за прехода към чиста енергия.

Design Proton-Conducting Metal Organic Frameworks based membranes for Proton Exchange Membrane Fuel Cell Applications

The MOF-PEMs project addresses one of the key challenges in the transition toward clean energy — the development of efficient, durable, and environmentally friendly materials for proton-exchange membrane fuel cells (PEMFCs). Conventional membranes such as Nafion rely on fluorinated polymers, which are expensive, environmentally persistent, and show performance loss under low humidity. The project set out to design and synthesise a new generation of fluorine-free, intrinsically proton-conductive porous materials, known as Metal–Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs). These materials combine the advantages of crystalline order, tunable porosity, and functional groups capable of conducting protons without the need for external dopants or additives. Initially, the research focused on phosphonate linkers, which offer excellent chemical stability. However, due to synthesis difficulties, the strategy was adapted to functionalised carboxylate linkers, particularly BTC-NH2 and SSA (sulfosuccinic acid). This change allowed for reproducible, green syntheses and led to the discovery of new classes of materials with intrinsic conductivity comparable to, or higher than, benchmark systems. The main goal of MOF-PEMs is to contribute to the European Green Deal and the Clean Hydrogen Partnership by providing sustainable alternatives to fluorinated PEM materials.

Цел на проекта

Proton exchange membrane fuel cells (PEMFCs), converting chemical fuels into electricity, are a promising electrochemical technology for the sustainable energy production using clean energy sources, thus, addressing the global challenge of energy demand and pollution control. However, drawbacks of the current polymer electrolyte materials (i.e, degradation and efficiency) limit their application. Metal-Organic Frameworks (MOFs), a class of hybrid porous materials, have recently found potential applicability in this emerging cross-disciplinary energy area. MOF-PEMs project aims to prepare new cost effective MOF-based membranes gathering good stability, and high proton conductivity over wide range of humidity and temperature conditions, supported by theoretical calculations toward understanding their proton-conducting pathways, which is an important step to industrially efficient PEMFCs. MOF-PEMs will, thus, overtake the current bottleneck of most commercial PEMs, by developing new electrolyte materials with high proton conductivity comparable or even surpassing Nafion® and affordable price, filling the gap between basic research and marketable applications. Key opportunities envisioned from MOF-PEMs include mitigation CO2 emissions and alternative sustainable energy-conversion and energy storage systems that are reliable, low-cost and environmentally friendly. We believe that the results of MOF-PEMs will attract large industrial interest derived by the need of society and governments for continued energy supply associated with rapid population growth.
