This Solution overcomes the adoption challenges of Fuel Cells technology, such as bulkiness, complexity and high costs.

This simplified and re-designed Solution stacks Fuel Cells at the micro level, making it significantly more compact, lightweight and efficient. It also simplifies the overall Fuel Cells system architecture by reducing or eliminating auxiliary components, making it more efficient and cheaper. The first-generation product delivers a power density of 1.5 times that of leading competitors’ products. This technology also integrates proprietary machinery that will enable the production at scale at a cost of less than 100CHF/kW (vs 1,000 CHFk/W currently). Lastly, this technology can operate with minimal effects of gravity and in any orientation, making it a great candidate in the mobility sector.
