A method for operating, especially for starting, a fuel cell such as a solid oxide fuel cell (SOFC) is disclosed which method includes a starting operation with a first or initial start phase and an optional second or intermediate start phase which is initiated when the fuel cell has reached a predetermined medium temperature below a steady state operational temperature range, before a steady state operation is activated. During the first or initial start phase fuel is subjected to an exothermic reaction with oxygen in a burner unit and output gases from the burner unit are used to warm up and passively heat the fuel cell. Furthermore, a fuel cell arrangement comprising a fuel cell, especially a SOFC hybrid system, for conducting this method is disclosed.

Method for operating a fuel cell and a fuel cell arrangement

An apparatus and method for substantially continuously manufacturing fuel cells are provided. Each cell generates electrical power from reactions of reactants therein. Each cell comprises component parts assembled and/or laminated together in a stacked configuration. The apparatus includes an assembly zone for receiving rolls of material and/or pre-formed component parts for fabricating the cells, and assembly devices for, commencing from a starting layer, progressively assembling and/or laminating layers of material and/or pre-formed component parts from the rolls to the starting layer to manufacture the fuel cells, a testing zone for applying a test procedure to the cells to identify functional cells thereof or parts thereof, the testing zone also including a fuel-cell repair function for recycling fuel cells, or parts thereof, found to be to be defective in response to applying the test procedure, a separating zone for mutually separating the functional cells into individual fuel cells, parts thereof or groups of such fuel cells, and a stacking zone for mutually assembling the functional fuel cells or the groups of such functional cells into stacks of such fuel cells to manufacture fuel cell packs.
