H2Sky

In H2sky, a fuel cell stack is being developed and pre-industrialized for use in the main propulsion system for aircraft. In order to meet the high requirements of the aerospace application, a fundamental adaptation of the materials used and the respective manufacturing processes is necessary. For the cell materials, novel ionomers and innovative design concepts are being developed and implemented on a large scale. At the stack level, both the flow fields and the stack configuration will be adapted to the mode of operation and the high requirements, and novel manufacturing concepts will be evaluated.
