Abstract: An integrated metal hydrogen-oxygen fuel cell system based on aluminum-lithium alloy is provided. By optimizing the element composition and surface morphology of the negative electrode of a metal-air cell, the working voltage of the cell is kept stable, and the hydrogen generation efficiency and stability are significantly improved. The 2195 aluminum-lithium alloy is selected as the negative electrode to enhance the electrochemical activity, and more reaction sites are exposed through the optimized morphology to ensure the continuous generation of hydrogen by side reactions, thus providing sufficient and stable fuel for hydrogen-oxygen fuel cells.

Abstract: Provided is a method, an apparatus, and an electronic device for task creation. The method includes: in response to a creation instruction, generating target task information, wherein the target task information is configured to characterize content of a target task, wherein the target task comprises at least one target task item, and the target task item corresponds to at least one target participating role; determining a corresponding target component based on the target task information, wherein the target component is a pre-generation component configured to implement a function of a target task item; creating a corresponding target task item for the target participating role based on the target component. The disclosure completes task creation for a target participating role, thereby improving the task creation efficiency.

Abstract: Embodiments of the disclosure provide a subscription processing method, apparatus, an electronic device and a readable storage medium. The method is applied to a client and comprises: when receiving a subscription request for a target service in the client, determining whether an application store account bound to the client has subscribed to the target service; if the application store account bound to the client has subscribed to the target service, determining whether the target service has been unsubscribed; if the target service has been unsubscribed, determining whether the target service is still in a subscription period; and if the target service is still in the subscription period, intercepting the subscription request. By applying the embodiments of the present application, the client platform may be prevented from suffering losses.
