Abstract: The present application relates to a warming-up control method for a fuel cell system in a starting process and a fuel cell system, applied to the technical field of fuel cells. The method includes: starting the fuel cell system, turning on a small-cycle cooling circuit, and pull-loading an output power to a first power; in response to an inlet temperature of a stack reaching a first temperature, rotating a three-way valve at a first rotating rate; calculating a variance of a cell voltage value; in response to the variance being smaller than a third threshold and reducing the variance to be within the first threshold, returning to the rotating the three-way valve at the first rotating rate until all turn-on of a large-cycle cooling circuit and all turn-off of the small-cycle cooling circuit; pull-loading the output power to a rated power.

Abstract: A drawer-type steamer includes a steamer drawer configured to be selectively withdrawn rearward or pulled forward. The steamer drawer includes: a steaming cavity, configured to accommodate a to-be-steamed object, where a rear wall of the steaming cavity has a steam inlet, and a front wall of the steaming cavity has a steam outlet; a steam generator, arranged behind the steaming cavity, where steam generated by the steam generator is configured to move forward to enter the steaming cavity through the steam inlet and move forward to exit the steaming cavity through the steam outlet. As a result, an efficient and convenient steamer can be provided.

Abstract: The present application relates to a startup control method and apparatus for a fuel cell system, an electronic device, and a medium, applied to the technical field of fuel cells. The method includes: setting a loading current as a first current value, in response to a monolithic voltage value of a stack being smaller than the first voltage value, decreasing the loading current; in response to the decreased loading current being larger than a second current value and the monolithic voltage value being larger than or equal to the first voltage value, running the fuel cell system for a period of time under the loading current, and then returning for setting the loading current as the first current value.
