Benefits of technology
[0008]During operation of the device, the electricity connector and pressing connector generally move to different positions with the help of a moving device, whereas the electrically conductive bar and the electrolysis stack remain still. Each polar panel includes a connector part configured to connect with the electricity connector; this facilitates variably including any number of panels in the electric circuit. The pressing connector is configured to press on the electricity connector, to ensure a smooth electricity connection between the electricity connector and the connector part on the polar panel. Beneficially, the disclosed structure of the electrolysis stack device provides an effective way to avoid friction during the capacity adjustment, secure the connection of the electric circuit and extend the lifetime of the moving parts.
Problems solved by technology
Renewable energy sources such as wind and solar power, however,are generally unstable and intermittent, and are therefore hard to be fully utilized by electrolyzers in an effective way.
The use of power electronics to stabilize the electricity input often leads to increased capital cost and efficiency loss, which currently prevents electrolyzers from being massively used in the clean energy industry.

Abstract
A configuration for an electrolysis stack device with adjustable operating capacity, including a specially shaped polar panel, an electricity connector and a pressing connector. A connection part of the polar panel and a pressing connector ensure that the electrical current can flow smoothly from a power source, via the electricity connector, to the electrolysis stack and back to the power source. In various embodiments, a zigzag track may help an electricity connector move to the correct position to vary the operating capacity of the electrolysis stack device.
Description
DESCRIPTION OF RELATED ART[0001]Hydrogen, a highly effective clean gas with zero greenhouse gas emissions when burnt, is deemed to be the leading energy carrier in the future.[0002]One of the technologies for generating hydrogen is water electrolysis. If the power source of an electrolysis system is renewable energy (e.g., wind power or solar power) instead of traditional fossil fuel, the resultant hydrogen gas becomes truly carbon free energy, emitting zero greenhouse gas during production and usage. Renewable energy sources such as wind and solar power, however,are generally unstable and intermittent, and are therefore hard to be fully utilized by electrolyzers in an effective way. The use of power electronics to stabilize the electricity input often leads to increased capital cost and efficiency loss, which currently prevents electrolyzers from being massively used in the clean energy industry.[0003]Many prior-art technologies are attempting to adjust the capacity of electrolysis...
