Fuel cell

Fuel cell cartridge architecture that feeds fuel into a cavity—unlocking drop-in, compact fuel-cell stacks without licensing.

What it is

The patent describes a fuel-cell fuel cartridge with a housing, an internal structure that defines a cavity, and an opening that places the stored fuel in fluid communication with the cavity for operation. This mechanical flow-path design is specific enough to support compact fuel delivery, enabling cartridge-style fueling rather than bulky fuel plumbing. Previously, implementing the same cartridge geometry and fluid-inlet architecture would likely require negotiating licenses with the assignee.

What you could build

Build cartridge-based portable power systems where a sealed fuel cavity delivers fuel to a compact fuel-cell stack.
