Hydrogen Compression Stack Manifold Layout for Low Deformation

The apparatus is divided into multiple compression units stacked in series, with gas introduction spaces provided between each compression unit and the end plates. This segmentation allows high-pressure gas to be distributed to multiple locations simultaneously, ensuring uniform pressure distribution and reducing localized deformation while maintaining low contact resistance across all interfaces.

Gas introduction spaces are pre-formed between the compression units and end plates during assembly, and high-pressure gas is introduced into these spaces before the compression units are fully tightened. This preliminary action allows the gas pressure to act as a cushion that prevents direct metal-to-metal contact and reduces deformation before the fastening members are fully secured.

The gas flow channel structure is extracted from the compression units themselves and relocated to the end plates. The end plates are equipped with gas introduction spaces and flow channels that directly distribute high-pressure gas to the interfaces between compression units. This extraction simplifies the overall device complexity by eliminating the need for complex internal gas channels within each compression unit, while maintaining effective gas distribution.

The end plates serve multiple functions: they provide structural support for stacking compression units, act as electrical connectors, and function as gas distribution manifolds. By integrating gas flow channel functionality into the end plates, the design achieves multi-functionality without increasing device complexity, as the same components perform multiple roles.
