Nicholas Gurieff gave a presentation on new concepts for alternative vanadium redox flow battery cell and stack designs. Initial studies showed that a tapered cell design provided slightly better performance than conventional rectangular cell designs. This new concept also allows the possibility for constructing toroidal stacks with potentially smaller space requirements. Jens Noack gave a presentation on current activities in the field of international standardization of redox flow batteries. This year the publication of three standards specifically developed for redox flow batteries is expected.
