Celadyne coats membranes with nanoparticles to make hydrogen fuel cells more efficient

The material could drastically improve the durability of existing fuel cell designs while also improving the efficiency of hydrogen production by 15%-20%.

Unfortunately, thicker membranes rob the system of efficiency, and they don’t totally solve the durability challenges that confront fuel cells. Celadyne’s business model cleverly addresses both sides of the chicken-and-egg problem, though its success in either will depend heavily on its ability to scale production of its nanoparticle coating. The company has its work cut out: Tackling both sides of the market, especially one that’s as underdeveloped as hydrogen, is a steep challenge for a seed-stage startup.
