NEW TYPE OF GLUEING OF REDOX FLOW STACKS
Keywords:Redox Flow, Stack, Glueing, Energy Conversion, Cost Reduction
For the energy transition to succeed, the growing amount of solar and wind power need to be stored for night-time or low-wind periods. Redox flow storage offers a good way of balancing out the fluctuations in renewable energies and is considered a promising energy storage system because it is potentially inexpensive and relatively easy to scale. However, the costs are still too high for this technology to be a resounding success. New manufacturing and joining technologies can help here. This will be demonstrated using the central element of the redox flow battery, the stack, as an example. Here, novel bonding ideas will be investigated and explained. The aim was to improve the contact between the gas diffusion fleece on the active side of the bipolar half plates and the current collector on the bipolar edge plates. A media and temperature-resistant adhesive was tested and tried out in different geometries.
