Abstract: A fuel battery module unit includes a fuel battery module and a controller. The fuel battery module includes a reformer and a fuel battery cell stack. The reformer generates fuel gas by reforming raw fuel gas. The fuel battery cell stack includes multiple fuel battery cells. The fuel battery cells generate power through a chemical reaction between the fuel gas generated by the reformer and an oxidant. The controller raises the temperature of the reformer from startup until start of generation of power in the fuel battery cell stack. The controller lowers the temperature of the reformer multiple times until the fuel battery cell stack starts generating power.

The gas supply pipe may include a first protruding portion protruding toward an inner side of the gas supply pipe and located at a position corresponding to the first joining portion in any cross-section along an insertion direction of the gas supply pipe.

Abstract: A resource collection apparatus is an apparatus for collecting waste reusable as a resource. The resource collection apparatus includes an opening associated with a predetermined sorting type, an opening/closing unit configured to open and close the opening, a first detector configured to perform an operation to detect a target waste belonging to a user, and a controller configured to specify a sorting type into which the target waste is to be sorted, by using a result of the detection by the first detector. The controller switches the opening/closing unit from a closed state to an open state when the specified sorting type matches the sorting type associated with the opening.

Abstract: A resource recovery system is a system for recovering articles which can be recycled as resources. The resource recovery system includes a resource recovery apparatus that recovers the article discarded by a consumer, and a server apparatus that communicates with the resource recovery apparatus. The resource recovery apparatus transmits, to the server apparatus, a first message including an article identifier for identifying the recovered article. The server apparatus associates, based on the first message received from the resource recovery apparatus, a discarding time when the article is discarded with a provision time when the article is provided to the consumer.
