Abstract

The invention relates to a fuel cell installation comprising a fuel cell unit (6). Said installation is also provided with a dosing unit (8) which comprises at least one dosing valve (7) and is used to dose a fuel (10) for at least one anode (12) of the fuel cell unit (6), and a starting valve for dosing the fuel (10) for at least one cathode (19) of the fuel cell unit (6) during a starting phase. The aim of the invention is to be able to produce and operate one such fuel cell installation in an economical manner. To this end, at least one throttle element (18) comprising a fixed internal cross-sectional area is used to fix the maximum quantity of fuel that can be dosed in the starting phase.
