Untapped potential: The unique opportunities of low-temperature and high-temperature hydrogen fuel cells
First practiced by General Electric researchers during the 1950s and later developed for the NASA Gemini Space programme in the 1960s, low-temperature proton exchange membranes (LTPEM) fuel cells have been the go-to hydrogen fuel cell technology for decades, thanks in part to significant investment from the US and Europe in LTPEM projects.LTPEM is well-known for its efficiency, power density, life, and ease of use when using pure hydrogen as a fuel. The technology has been refined over the decades by some of the world’s great chemical and membrane companies and is making significant inroads into power generation markets such as transportation, material handling, and backup power. Using pure deionised water as an electrolyte, the membrane (usually Nafion™) situated between…
