Giner Labs Legacy Electrolyzer Stacks are specialty proton-exchange-membrane (PEM) electrolysis stacks developed for lightweight and space-constrained applications, including submarine life-support, aerospace and laboratory gas-generation duties. The technology can generate high-purity oxygen above 99.999% while producing hydrogen as the corresponding electrolysis product. Giner states that its high-pressure aerospace electrolyzers can produce gas streams at pressures up to 80 bar, with development work targeting operation at 140 bar for NASA. The PEM stack architecture is designed for compact, durable and high-current-density electrolysis applications.
