The Technology

Alkaline fuel cells and electrolyzers offer many advantages over their acidic counterparts, the main one being the possibility to replace precious metals in electrodes with other, low cost and abundant metals. However, the alkaline environment leads to substantial electrolyte decomposition – an anion exchange membrane (AEM) – limiting the operating hours of the devices. Moving away from classical chemistries, new polymers with protected cations leads to AEMs with unparalleled alkaline stability.
