However, several hurdles such as cost, durability, efficiency and resource scarcity need to be overcome before it can be widely adopted.<\/p>\n<p style=\"text-align: justify;\" data-end=\"1530\" data-start=\"812\">The HYScale team has taken up this challenge. As described in an article on the project website: &#8220;HYScale is scaling up innovative, high-performance materials that reduce dependence on scarce resources, without compromising performance or efficiency. The project has replaced the fundamental raw materials and PFASs traditionally used in anion exchange membrane (AEM) water electrolysers, a technology used in hydrogen production. Instead, a more economical and environmentally friendly alternative is being developed: the first 100 kW single cell AEM electrolyser prototype.<\/p>\n<p style=\"text-align: justify;\" data-end=\"2120\" data-start=\"1532\">Tests have shown that the new materials developed at HYScale can be scaled up without compromising performance. &#8220;Large-scale applications now offer results that match those obtained in small-scale single-cell laboratory tests, a crucial milestone on the road to real-life application,&#8217; the paper reports. In doing so, the project is &#8216;one step closer to integrating the battery into a fully functional electrolyser system&#8217;. The HYScale team is aiming for a capital expenditure of EUR 400\/kW and is moving towards industrial validation.<\/p>\n<h3 style=\"text-align: justify;\" data-end=\"2154\" data-start=\"2127\"><strong data-end=\"2154\" data-start=\"2131\">Getting to this point<\/strong><\/h3>\n<p style=\"text-align: justify;\" data-end=\"2537\" data-start=\"2156\">To scale up to a complete electrolyser system, the HYScale team first had to optimise the individual cell components. They worked to refine the catalysts, membranes and porous transport layers of the small-area cells to ensure the efficiency, durability and long-term operation of each component.<\/p>\n<p style=\"text-align: justify;\" data-end=\"3122\" data-start=\"2539\">The <strong data-end=\"2594\" data-start=\"2542\">Italian National Research Council (CNR)<\/strong>, a project partner, investigated the influence of the substrate used for the electrode. They also analysed the type of porous transport layer, designed and manufactured by Belgian project partner <strong data-end=\"2783\" data-start=\"2772\">Bekaert<\/strong>. The project coordinator, <strong data-end=\"2858\" data-start=\"2848\">CENmat<\/strong>, provided catalyst-coated substrates using high-performance non-core raw material catalysts. The CNR and its German partner <strong data-end=\"3021\" data-start=\"3014\">DLR<\/strong> conducted extensive tests to assess the performance and stability of the components.<\/p>\n<p style=\"text-align: justify;\" data-end=\"3410\" data-start=\"3124\">To meet scalability goals, the project team also developed a <strong data-end=\"3243\" data-start=\"3215\">large-area cell<\/strong>. The design incorporates specialised solutions for the frames and the sealing and transport layers, and has been optimised to minimise machining steps.<\/p>\n<p style=\"text-align: justify;\" data-end=\"3852\" data-start=\"3412\">A <strong data-end=\"3462\" data-start=\"3433\">flow-field-free design<\/strong> was also adopted. CNR researcher <strong data-end=\"3495\" data-start=\"3475\">Nicola Briguglio<\/strong> explains: &#8220;The decision was driven by the need to simplify the architecture of the AEM short stack and reduce manufacturing complexity. In addition, the elimination of the flow field reduces the overall thickness of the stack and facilitates a more compact and lightweight design, which is beneficial for system integration and scalability.<\/p>\n<p style=\"text-align: justify;\" data-end=\"4339\" data-start=\"3854\">Testing is already underway as part of the short stack phase.
