Latest Patents
Among his latest inventions is the "Apparatus for improving the cold starting capability of an electrochemical fuel cell." This innovative system enhances the cold start capability and freeze tolerance of a fuel cell stack by reducing the amount of water remaining in its passages. The invention features a purge system that connects to the oxidant supply, fuel supply, and coolant passages, allowing for the transmission of purge fluid through the stack before the temperature drops below freezing. Additionally, in systems where reactant streams are humidified, a humidifier bypass system is included, ensuring that inlet reactant streams remain unhumidified.
Another notable patent is the "Method and apparatus for increasing the temperature of a fuel cell." This method increases the temperature of a fuel cell by implementing reactant starvation at one or both electrodes, resulting in enhanced internal heat generation under load. By prolonging or intermittently applying starvation conditions, van der Geest's method enables some generation of useful power during startup, specifically for solid polymer electrolyte fuel cells initiated from sub-zero temperatures.
