Princeton Uni control hydrogen flow for advanced fuel cell
Conventional fuel cells are typically far more complicated than the Princeton design and feature networks of serpentine channels to combine the reactive hydrogen and oxygen gases, maintain the suitable humidity levels and remove water from the system. In such a system, water droplets can clog the narrow channels, leading to inefficient and irregular power production. The Princeton design mixes the gases via diffusion in a simple reaction chamber and relies on gravity to drain the water produced.
Expected initial applications of the design include lawn mowers, which are currently unregulated in regards to emissions, and other small machines.
