Abstract:
A transportable solid oxide fuel cell and balance of plant in a portable enclosure. A fuel supply is provided in the enclosure. The fuel supply is refillable. Power conditioning of the electricity provided is also provided as part of the enclosure.
Abstract:
The present disclosure provides an alternative, cost-effective safety feature for on-board hydrogen storage containers incorporating a fill cycle sensor with a driver warning and shutdown system. The system monitors the number of times a hydrogen container is filled, and then takes action at a predetermined termination point. A controller monitors each time the hydrogen container is filled above 90% of the rated pressure or mass. Once the predetermined termination point of fill cycles is reached, the disclosed device/method will either disable the valve or refueling mechanism such that fuel supply to the vehicle is shutoff and the container cannot be filled again, essentially assuring the end of the life of the container.
Abstract:
Devices and methods for storing hydrogen fuels or other gaseous fuels (e.g. hydrogen). One embodiment of a container (20) for storing gaseous fuels in accordance with an aspect of the invention comprises a high-pressure vessel (22) configured to contain the gas in a high-pressure zone at a pressure significantly above atmospheric pressure (e.g. 300-10,000 psi). The container (20) can also include a storing medium (40) in the vessel (22) and an inlet/outlet line (50) extending through the vessel (22). The storing medium (40) can have a plurality of storage spaces (28) configured to physically bind molecules of the gas to the storing medium (40), and the inlet/outlet line (50) can be a tube (52) extending through the vessel (22) in fluid communication with the storing medium (40). The molecules of the gaseous fuel bind to the storing medium (40), and the pressure in the vessel drives additional molecules of the fuel into vacant spaces within the storing medium . A heater (60) is used to release hydrogen from the medium (40).
