Abstract
An airship and its long-term floating capacity maintenance method are disclosed. The airship includes an airship capsule and a pod at bottom. A renewable fuel cell and a water tank communicated with each other are arranged in the pod. The water tank is provided with a water inlet connected with a filling aircraft outside the airship. The airship capsule is provided with a solar cell. The interior of the airship capsule is provided with a hydrogen storage bag. The solar cell is electrically connected with the renewable fuel cell. The renewable fuel cell can use electric energy provided by the solar cell to electrolyze water provided by the filling aircraft into hydrogen and supplement the hydrogen to the hydrogen storage bag. The airship can supplement hydrogen to the airship capsule by electrolyzing water to reduce the phenomenon of insufficient gas in the airship capsule.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
