NOVELTY - The cell (100) has a current collector (120) formed in flat shape including two surfaces (120a, 120b), where one of the surfaces includes a groove formed along thickness direction to receive a unit cell (110). A circular support unit (121) is formed between the surfaces of the current collector, provided in the support unit for regions and includes different diameters. The groove including shape surrounds a portion of the unit cell, which includes two electrodes and an electrolyte. The surface of the collector is formed in a mesh structure.    USE - Solid oxide fuel cell for generating energy i.e. electricity, from alternative energy sources of hydrogen and petroleum, Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas/Liquid Propane Gas (LPG).    ADVANTAGE - The cell directly transforms chemical energy of fuel into electric energy by electrochemical reaction. The cell has high theoretical efficiency such that fuels are usable without using modifier. The cell improves current collection resistance at time of current collection in the unit cell in an efficient manner. The support unit is formed within the current collector, so that better contact conditions between the unit cell and the current collector can be maintained, thus reducing contact resistance, and hence improving contact condition between the unit cell and the current collector. The cell allows a path of collected current that can be shortened and a set of paths for current flow can be formed, thus improving performance of the cell. The cell allows a structure for current collection to be simplified, thus reducing manufacturing procedure and manufacturing cost of the cell.    DETAILED DESCRIPTION - The support unit is made of flexible material. The cell has cylindrical shape. The support unit includes a coating layer made of silver or conductive ceramic material. The support unit is made of metal material that is selected from a group consisting of Steel Use Stainless (SUS) i.e. stainless steel Material, Crofer, Zionstyles Marketing Group (ZMG) metal and Nickel (Ni) metal.
