A method of manufacturing a membrane-electrode assembly includes: forming an electrolyte membrane containing an ionomer on a base material; applying an electrode slurry containing a catalyst, a binder, and a solvent to a first surface of the electrolyte membrane to form a structure including the electrolyte membrane and an electrode layer laminated on the first surface of the electrolyte membrane; and delaminating the structure from the base material.

Method of manufacturing membrane-electrode assembly by directly coating electrode layer on electrolyte membrane

Disclosed are an electrode for fuel cells, a membrane electrode assembly for fuel cells including the same and a method for manufacturing the same in which the electrode is manufactured by forming an ionomer layer between an electrode layer and a catalyst layer and an antioxidant is dispersed into the catalyst layer of the electrode and an ion exchange layer of an electrolyte membrane so as to improve interfacial bonding force between the electrode and the electrolyte membrane, the electrode is bonded to the electrolyte membrane using a transfer process, and durability of the electrode and the electrolyte membrane is improved.

A pedal apparatus comprises a pedal housing including an inner space, a pedal pad configured to rotate relative to the pedal housing, a pedal arm connected to the pedal pad, a magnet installed in the pedal arm, and a sensing board. The pedal arm includes a hollow and is configured to rotate based on a rotation of the pedal pad. The sensing board has at least a portion inserted into the hollow and includes a hole sensor configured to sense a magnetic force generated by the magnet.

Pedal apparatus and manufacturing method thereof

A sensorless control method for a motor performed by a sensorless controller including a back electromotive force (EMF) observer and a phase locked loop (PLL) controller, includes: estimating a back EMF of the motor using the back EMF observer; calculating an electrical angle error in accordance with iron loss of the motor based on the estimated back EMF; and compensating for the calculated electrical angle error, inputting the compensated electrical angle error into the PLL controller to estimate an actual angle, and controlling the motor based on the estimated actual angle.
