A control method for a fuel cell system, the fuel cell system including a hydrogen storage part and a fuel cell stack that generates electric power using hydrogen supplied from the hydrogen storage part, the fuel cell system being mounted on a towed portion of a moving body that includes the towed portion and a towing portion, the fuel cell system being electrically connected to the towing portion, the towing portion including a battery and a drive device performing driving in response to supply of electric power, the towed portion being towed by the towing portion, the control method includes: acquiring remaining amount information indicating a remaining amount of the battery, and starting supply of electric power to the towing portion when it is determined that the remaining amount of the battery is equal to or less than a threshold based on the remaining amount information.

A fuel cell vehicle includes a cabin arranged at a vehicle front portion and provided with a seat therein where an occupant is seated, a fuel cell mounted below the cabin, and an accommodation space formed below the cabin and accommodating the fuel cell. An upper side of the accommodation space is covered with a ceiling surface formed by a bottom portion of the cabin, and a rear side of the accommodation space is opened. The ceiling surface is provided with a detector configured to detect a hydrogen concentration in the accommodation space.

In a non-contact power supplied electric vehicle or a non-contact power supplying method, when a request for starting non-contact supply of power is made, if it is determined that interference occurs between a charging frequency or a higher harmonic component thereof and a radio frequency, the charging frequency is changed to a frequency that is capable of avoiding the interference. Non-contact supply of power is allowed to be started under a condition in which the charging frequency has been changed to a frequency that is capable of avoiding the interference.

An air-fuel ratio control system for an internal combustion engine has a perturbation control which oscillates the air-fuel ratio with a first frequency. A first difference signal is generated indicative of a difference between a present value and a first past value from an air-fuel ratio sensor detected at a timing of a first specific period which is set to reduce a specific frequency component corresponding to a specific frequency different from the first frequency. A first frequency component is extracted. A second difference signal is generated indicative of a difference between a present value and a second past value detected at a timing of a second specific period which is set to reduce the first frequency component. The specific frequency component is extracted. A failure of the control system is determined by a relationship between intensities of the first frequency component and the specific frequency component.
