Electronic device and method for transmitting data by using messenger application

A cooling plate in which flow channels are modified to reduce temperature differences between portions of the cooling plate and provide for more uniform heat distribution within a heat generator. The flow channels of the cooling plate are formed such that a central portion of the flow channels has a greater volume than the end portions near an inlet and an outlet so that the amount of cooling water that is contained in the central portion at any one time is larger than either of the end portions near the inlet and the outlet. Likelihood of thermal deformation of the cooling plate due to thermal stress is decreased, and stability of performance of the fuel cell is increased.

Cooling plate having improved flow channels

Bipolar plates and a fuel cell stack having the bipolar plates. The fuel cell stack includes membrane electrode assemblies (MEAs), and first and second bipolar plates sequentially stacked between the MEAs. The bipolar plates include: flow channels formed on opposing surfaces thereof; four manifolds connected to the flow channels; and through holes to connect to the manifolds of the bipolar plates adjacent thereto.

Bipolar plate and fuel cell stack including the same

A bipolar plate includes a plurality of flow channels for fuel flow, wherein the flow channels are divided into a plurality of sections along a direction of the fuel flow. The total cross-sectional area of the flow channels across the sections becomes smaller from a fuel inlet toward a fuel outlet. A plurality of protrusions are formed between the sections, and the protrusions mix a fuel that passes through the flow channels. A fuel cell includes membrane electrode assemblies interposed between a plurality of the bipolar plates.

The invention relates to a pulse width modulator, more particularly to a cross-coupled pulse width modulator. A crossing input signal modulator according to the present invention comprises: a positive path block which includes a first integrator for performing the first-order integration of feedback signals in first input and output signals and then transmitting the first-order integrated signals to a second integrator, and a second integrator for performing the second-order integration of a signal from the first integrator and a second input signal and then transmitting the second-order integrated signals; and a negative path block which includes a third integrator for performing the first-order integration of feedback signals in the second input and output signals and integration of a signal from the third integrator and the first input signal and then transmitting the second-order integrated signals. This configuration allows cross-coupling of the inputs from two integrators to generate an accurate differential pulse width modulation (PWM) single, and enables optimization of the IC implementation by adopting a feedback system that features a simplified implementation and minimal application area.
