  title = {A non-precious metal hydrogen catalyst in a commercial polymer electrolyte membrane electrolyser},
  abstract = {<p>We demonstrate the translation of a low-cost, non-precious metal cobalt phosphide (CoP) catalyst from 1&thinsp;cm2 lab-scale experiments to a commercial-scale 86&thinsp;cm2 polymer electrolyte membrane (PEM) electrolyser. A two-step bulk synthesis was adopted to produce CoP on a high-surface-area carbon support that was readily integrated into an industrial PEM electrolyser fabrication process. The performance of the CoP was compared head to head with a platinum-based PEM under the same operating conditions (400&thinsp;psi, 50&thinsp;°C). CoP was found to be active and stable, operating at 1.86&thinsp;A&thinsp;cm−2 for&thinsp;&gt;1,700&thinsp;h of continuous hydrogen production while providing substantial material cost savings relative to platinum. This work illustrates a potential pathway for non-precious hydrogen evolution catalysts developed in past decades to translate to commercial applications.</p>},
