An electrode assembly for a battery. The electrode assembly includes a positive electrode with a positive electrode active material layer and a negative electrode with a negative electrode active material layer. The assembly further includes a separator that has a porous layer formed of a ceramic material and a binder and a polyolefin resin layer. The porous layer has a thickness of about 4 to 6 &#x3bc;m and the polyolefin resin layer has a thickness of about 12 to 16 &#x3bc;m.

Electrode assembly and secondary battery having the same

A fuel cell system includes at least one electricity generating unit for generating electric energy through an electrochemical reaction between oxygen and hydrogen, a reformer for reforming fuel to generate hydrogen gas to be supplied to the electricity generating unit, a fuel supply apparatus for absorbing a liquid fuel stored in a fuel reservoir and supplying the fuel to the reformer and an oxygen supply source for supplying oxygen to the electricity generating unit. The fuel supply apparatus employs an absorber with capillary channels in which osmotic pressure is produced due to a concentration differential caused by thermal energy. The osmotic pressure allows the fuel to flow.

Fuel cell system including fuel supply apparatus

A secondary battery includes: a bare cell having an electrode assembly including two electrodes and a separator arranged between the two electrodes, a cell container having an opening and adapted to contain the electrode assembly, and a cap assembly adapted to cover the opening; and an accessory unit having a protective circuit module and adapted to be electrically connected to the bare cell via at least one electrode from outside of the bare cell. The accessory unit is adapted to be affixed to the bare cell with an adhesive member arranged in at least a portion of facing surfaces of both the bare cell and the accessory unit.

Secondary battery

Battery management system and a driving method thereof including a sensing unit and an MCU. The sensing unit measures a battery current and a battery voltage. The MCU sets an OCV during a no-load state period at time increments measured from the beginning of the no-load state period, and estimates an SOC corresponding to the set OCV.

Battery management system and driving method thereof

A fuel cell system includes a stack for generating electricity through an electrochemical reaction between hydrogen and oxygen, a fuel supply unit for supplying fuel to the stack, an air supply unit for supplying air to the stack, and a vaporizing unit connected with the stack and for vaporizing moisture discharged from the stack.

Fuel cell system

A battery pack includes a case having an inner space, a plurality of battery cells placed inside the case, and at least one spacer placed between the battery cells. A space is formed around a supporting portion of the spacer for the battery cells so as to allow heat generated by the battery cells to flow out of the case. The spacer supports the battery cells by line contact therewith. The spacer body is formed in the shape of an H beam or in the shape of a staircase.
