Improving efficiency & lifetime of fuel cells

In the fuel cell market, many companies are competing, and it is a “winner take all” environment. You need to be first to market and do it right. If not, there could be repercussions for your brand. Material selection will have a strong influence on first-time right by improving lifetime, efficiency and safety.

Fuel cell systems need to use materials that are pure. If not, ion leaching and hydrolytic and heat aging can occur. These two failure modes and the risks and consequences can hurt your brand image. Impure materials increase the risk of ion leaching, and higher water absorbing materials show more ion leaching, which you do not want. Also, impure materials increase the risk of hydrolytic and heat ageing— PA9T and PA66 are not good performers.

Fuel Cells innovation insights

  • Helping you exceed the service life of fuel cell transport vehicles

    Combining the best of the electric vehicle and internal combustion engine worlds, proton-exchange membrane fuel cells (PEMFC) offer emissions-free driving of an EV with the range and convenience of a traditional ICE. Manufacturers must ensure the PEMFC is reliable and doesn’t degrade in hot water or a mild acid environment to meet and exceed the long service life of commercial transport vehicles.

  • Manufacturing long-lasting fuel cells for transport vehicles

    Industrial leaders are making massive investments in promoting fuel cell systems –primarily in proton exchange membrane fuel cells (PEMFCs), which offer low working temperatures, short start up times, the ability to run on ambient air, and easier electrolyte management. This is crucial for transport vehicles, which are built to travel long distances while maintaining a long service life. The first OEMs to launch PEMFCs optimized for the needs of transport vehicles will achieve a substantial competitive advantage.
