The following items are within the scope of this topic, which comprise both low and high temperature electrolyser and fuel cell technologies:

• Development, characterisation and validation of novel materials free of critical raw materials, non-sustainable or environmentally unacceptable components, or with reduced content of such critical materials or components in fuel cells and electrolysers to levels consistent with the SRIA targets without compromising their performance and durability;
• Development of innovative materials, coatings, processing routes, electrode architectures and cell designs to reduce platinum group metal and other CRMs loading in electrolysers and fuel cells;
• Development of breakthrough high-efficiency solutions for recycling the critical materials and critical components of fuel cells and electrolysers, including associated separation steps, with focus on recycling of perfluoro sulfonic acid ionomers for reuse, and on recycling of iridium. Industrially mature technologies are already in use for platinum recycling, however, solutions designed to reduce the potential environmental impact of non-Pt components of a Pt alloy (for instance, non-exclusively, Ni and Co) within the recycle stream are within the topic scope;
• Lifecycle analyses of the most prospective new technology/ies to demonstrate the sustainability of the proposed solutions.

The development of characterisation and test methods and protocols for evaluation of new and recycled materials and of complete cells is considered within the scope of the topic, however alignment should be made with those in use to qualify current state-of-the-art materials (i.e. those using critical raw materials, platinum group metals and perfluoro sulfonic acid membranes and ionomers).
