Hydrogen Optimized demonstrates new electrolyser

Ruggedcell is a unipolar design that allows high current through a single cell, unlike conventional alkaline and PEM electrolysers

Canadian hydrogen technology company Hydrogen Optimized announced a successful demonstration of a 50,000 amp version of its Ruggedcell water electrolyser in late October. The breakthrough provides a direct pathway towards commercialisation of large-scale green hydrogen production technology, as single electrolysis units can be sized at 100MW and potentially even larger than that in the future.  The Ruggedcell is a unipolar design based on the ‘Stuart Cell’, developed by the grandfather of Andrew Stuart, president and CEO of Hydrogen Optimized, in 1913. This original design—unlike the bipolar design used by alkaline and proton-exchange membrane (PEM) electrolysers, allows for larger volumes o
