An object of the present invention is to provide an adhesive composition having an excellent adhesive force even in the presence of hot water in an assembly in which at least one of two or more members to be bonded to each other via the adhesive composition is a low-polarity metal member, and an adhesion method. The present invention relates to an adhesive composition and an adhesion method for bonding a metal member. The adhesive composition contains a polyolefin (A) component having an acidic group and/or an acid anhydride group and having an acid value of 0.01 mgKOH/g to 6.5 mgKOH/g. The metal member has a ratio of a dipole term in surface free energy of 0.01% to 5.0%.

The invention relates to a production plant for producing a membrane electrode assembly or a membrane electrode frame assembly having multiple work stations in which successive production steps take place. The production plant according to the invention is characterized in that a main line and at least one secondary line are provided, wherein the at least one secondary line branches off from the main line after a central work station and, after at least one decentralized work station in the respective secondary line, reenters the main line before the central work station, wherein the central work station comprises at least one work section for an adhesive application, and wherein at least some of the decentralized work stations are designed at least for joining and/or positioning other materials and/or layers. The invention also comprises a method for producing a membrane electrode assembly or membrane electrode frame assembly using such a production plant.

An MG-ECU obtains a rotational speed Na of an ACP. The MG-ECU transmits the obtained rotational speed (a PM reception rotational speed) Na of the ACP to a PM-ECU through communication. The PM-ECU obtains a rotational speed predicted value Np by adding a rotational speed change width Cvw to the PM reception rotational speed Na received from the delayed MG-ECU. A limit torque Tr12 is obtained through the use of the obtained rotational speed predicted value Np and an ACP permissible power level line L1.
