ReliOn announced that it has received a U.S. patent for a new architecture for its E-Series of fuel cells. The architecture relies on simpler and more automated assembly, which in turn will result in lower-cost products, the company said. ReliOn does not use complicated bipolar plates or flow fields. The advancement consists of a plate and plastic frame architecture that simplifies manufacturing and allows for advanced air-cooling and membrane management, increasing the durability and efficiency of the products.
