Latest Patents

Schembri's latest patents showcase his innovative mind and commitment to advancing fuel cell applications.

1. **Fuel Cell Purging Method and Apparatus**: This invention involves a purge system for a fuel cell stack that utilizes a purge valve. The valve regulates exhaust from the fuel cell stack based on control signals from a controller, which responds to the voltage across a purge cell portion. If the voltage drops below a defined percentage of a threshold voltage, the purge valve opens. The threshold voltage corresponds to the average cell voltage across the fuel cells, allowing for controlled purges of varying durations.

2. **Fuel Cell Resuscitation Method and Apparatus**: This technology employs a fuel cell system with distinct fuel and oxidant passages. It features a purge valve linked to the fuel passage for contaminant exhaust and a controller that can temporarily increase the oxidant stream flow rate through the oxidant passage. If the voltage across a pair of fuel cells falls below a defined threshold, the system triggers a series of actions aimed at restoring functionality, including increasing the air compressor's duty cycle and opening the fuel purge valve.
