Abstract
Electrolysis splits water with the use of electricity into oxygen and hydrogen, which can then be stored as an energy carrier. Fuel cells reverse this process and thus generate electricity. Together, both systems are the basis of a future hydrogen economy, which allows storing and releasing large amounts of energy, e.g. from renewables. We applied additive manufacturing to fuel cells and fabricated the “heart” of the fuel cell, the membrane electrode assembly, in a single spray process instead of several processes. Besides being simpler the fuel cells exhibited a 40% higher peak power. Furthermore, the mechanical and chemical stability was increased by integrating nanofibers and nanoparticles. Thanks to additive manufacturing the spatial resolved deposition of materials is possible. This saves material and allows optimizing the membrane electrode assembly, e.g. by adjusting the catalyst content according to the reaction profile.
