    摘要： A membrane-electrode binder for a fuel cell, a method of manufacturing the binder, and a fuel cell comprising the binder are provided, in which the membrane-electrode binder comprises a dual electrode constituted by a first electrode and a second electrode in a two-layer form, and a polymer electrolyte membrane disposed on the dual electrode, the dual electrode comprising an electrode substrate and a catalyst layer formed thereon. In detail, the membrane-electrode binder comprises the dual electrode that is constituted by the first electrode obtained by using a PBI-based binder, the second electrode obtained by using a PTFE-based binder, and an inorganic acid doped PBI-based polymer electrolyte membrane disposed on the dual electrode and coming in contact with the first electrode. In the configuration of the dual electrode, the PBI-based binder used for manufacturing the first electrode contributes to enhancing an adhesive strength with the inorganic acid doped PBI-based polymer electrolyte membrane, and the PTFE-based binder used for manufacturing the second electrode contributes to suppressing the emission of an inorganic acid from the inorganic acid doped PBI-based polymer electrolyte membrane, together improving the performance of a fuel cell.

    摘要： A duty cycle corrector includes a first controllable delay, a second controllable delay, a phase detector, and a compensation circuit. The first controllable delay is configured to delay a first signal to provide a second signal. The second controllable delay is configured to delay the second signal to provide a third signal. The phase detector is configured to adjust the first controllable delay and the second controllable delay to phase lock the third signal to the first signal. The compensation circuit is configured to compensate for a mismatch between the first controllable delay and the second controllable delay to provide a fourth signal in response to the first signal and a fifth signal approximately 180 degrees out of phase with the fourth signal in response to the second signal.
