  • Polymer Electrolyte Fuel Cell-Based Power System for Long-Term Operation of Leave-In-Place Sensors
    Publication number: 20180090776
    Abstract: A method for power delivery comprising the steps of coupling a polymer electrolyte membrane fuel cell (PEM-FC) to a load system, wherein the PEM-FC is powered by hydrogen gas and oxygen; using a blower to deliver oxygen to the PEM-FC; using an automated electro-chemical control system to monitor PEM-FC hydrogen gas levels, PEM-FC voltage, and load demands; determining that more hydrogen gas is required to fuel the PEM-FC, mixing sodium borohydride, a catalyst, and water, releasing hydrogen gas and delivering the hydrogen gas to the PEM-FC, and transferring the resulting power from the PEM-FC to the load system.
