Abstract: A sheet having undergone the process of applying catalyst ink onto at least part of a surface of a transported sheet to a predetermined thickness is dried so that a solvent evaporating from the catalyst ink is recovered, and the sheet having undergone the process of transferring a catalyst layer formed on the transported sheet after the solvent evaporates onto another member so that the catalyst layer is removed is cleaned by using the recovered solvent as cleaning liquid so that at least part of the residue of at least the catalyst ink left on the sheet is removed. The thus cleaned transported sheet, when the usage count thereof is smaller than or equal to a quality assurance count, is reused in the application of the catalyst ink. As a result, in the manufacture of the catalyst layer using the catalyst ink, the amount of emission toward the outside is reduced.

Abstract: A battery electric vehicle includes a driving operation member for driving the vehicle, a processing circuit, and a memory storing a database that manages vehicle models obtained by modelling virtual vehicles among which acceleration characteristics for a driver's driving operation vary. The processing circuit is configured to read, from the database, a vehicle model of an intended virtual vehicle selected from among the virtual vehicles by the driver, acquire an operating status of the driving operation member and a driving condition of the battery electric vehicle, calculate a virtual acceleration of the intended virtual vehicle for an operation to the driving operation member based on the operating status of the driving operation member and the driving condition of the battery electric vehicle by using the vehicle model of the intended virtual vehicle, and control the electric motor such that an acceleration of the battery electric vehicle becomes the virtual acceleration.
