A recently filed patent (Publication Number: US20230268535A1) describes a stabilised DC voltage power generation system. The system includes a control unit and at least one circuit arm with multiple fuel cell modules connected in series. Each fuel cell module has a bypass connected in parallel to the module, and also includes a DC/DC converter that receives control signals from the control unit.

In addition to the above configuration, the system can also include a second circuit arm connected in parallel to the first arm. Both arms have the same quantity of installed fuel cells connected in series. Furthermore, the system can have multiple circuit arms interconnected in parallel, with each arm having the same quantity of installed fuel cells connected in series.

The bypass in the fuel cell modules is connected to the control unit to receive control signals. The DC/DC converter used in the system is of the step-down type.

Overall, this patent describes a stabilised DC voltage power generation system that utilizes fuel cell modules and a control unit to regulate the generation of DC voltage. The inclusion of bypasses and DC/DC converters allows for improved control and stability of the system. The system can be configured with multiple circuit arms connected in parallel, providing scalability and redundancy. The use of a step-down type converter further enhances the efficiency of the system.

This patent presents a novel approach to stabilizing DC voltage power generation, which could have applications in various industries such as renewable energy, electric vehicles, and telecommunications. The system's design allows for flexibility and reliability, making it suitable for different power generation requirements. Further development and implementation of this technology could lead to more efficient and stable DC voltage power generation systems in the future.
