Abstract
Method and apparatus for establishing a fuel cell unit (10) in the form of an extruded monolith having channels (14), of which every second constitutes a fuel channel (14a) and every other second an oxygen channel (14b). The channels (14) are designed in such a manner that the fuel channels (14a) are displaced laterally in relation to the oxygen channels (14b), in such a way that all the fuel channels (14a) protrude a certain distance from the end points of all the oxygen channels 14b) and all the oxygen channels (14b) protrude a certain distance from the end points of all the fuel channels (14a). The distance is less than the length of respective channels. The invention also relates to a fuel cell device that includes several of the fuel cell units (10) that together establish an enhanced system of fuel cell units that lend themselves to compact.
