High-Powered Fuel Cell Boosts Electric-Powered Submersibles, Drones (image) Washington University in St. Louis Share Print E-Mail Caption This is an artistic representation of the pH-gradient enabled microscale bipolar interface (PMBI) created by Vijay Ramani and his lab. The two layers that make up the interface are covering the third bottom layer, which is the electrode with palladium particles on it. The submarine and drones are envisioned applications of the direct borohydride fuel cell which incorporates the PMBI.
