摘要:
The present invention provides a heating device for an end plate of a fuel cell stack, which can prevent a decrease in temperature of unit cells around the ends of the fuel cell stack by providing a structure for circulating high temperature coolant discharged from the fuel cell stack in the end plate. Non-uniform temperature distribution in the fuel cell stack can thereby be prevented. In particular, a heating device for an end plate of a fuel cell stack is provided wherein high temperature coolant flowing from the upstream of a coolant outlet manifold to the downstream is allowed to circulate through the inside of the end plate and to be discharged to the outside such that the thermal energy of the coolant is supplied to the end plate and, at the same time, transferred to unit cells adjacent to the end plate.

An electric double layer capacitor (EDLC) includes an electric double layer cell and first and second external electrodes. The electric double layer cell includes a separator and at least one first polarizable electrode and at least one second polarizable electrode. The first and second external electrodes are formed at first and second side surfaces of the electric double layer cell facing each other, respectively. The first polarizable electrode includes a first current collection layer and a first active material layer formed on either surface of the first current collection layer facing the separator and the second polarizable electrode includes a second current collection layer and a second active material layer formed on either surface of the second current collection layer facing the separator.

A motor includes a stator and a rotor rotated due to the interaction between the rotor and the stator. Since overhangs are protruded only from the circumference of a rotor core of the rotor facing the stator in the axial direction, manufacturing costs for improving performance and core loss of the stator are minimized. Additionally, since the rotor core is manufactured by iron powder metallurgy, the rotor core is conveniently designed.

An apparatus and method for decoding digital stream data includes detecting a discontinuous period of digital stream data stored in a buffer, such that upon detection of the discontinuous period, a further operation includes decoding all currently stored portions of the digital stream data in the buffer using non-updated reference time information. The non-updated reference time information may be defined as the reference time information used for decoding the digital stream data prior to the discontinuous period. An additional operation includes decoding remaining portions of the digital stream data using updated reference time information.
