The invention relates to a fuel cell installation comprising a fuel cell unit (). Said installation is also provided with a dosing unit () which comprises at least one dosing valve () and is used to dose a fuel () for at least one anode () of the fuel cell unit (), and a starting valve for dosing the fuel () for at least one cathode () of the fuel cell unit () 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 () comprising a fixed internal cross-sectional area is used to fix the maximum quantity of fuel that can be dosed in the starting phase.

Fuel cell system with a metering unit

A valve for controlling a fluid, in particular for controlling a gas. The valve includes a valve housing which accommodates an electromagnetic actuating unit for a solenoid armature which is guided axially displaceably in the valve housing and which cooperates with a valve seat via a valve-closing member, so that a fluid stream from an inflow side to an outflow side of the valve is controllable. At least one lubricant chamber adjacent to the guide gap between the valve housing and the solenoid armature is provided.

Valve for controlling a fluid

A safety system for a gas-operated apparatus for generating energy, in particular in a vehicle, includes at least one sensor for measuring the gas concentration. The sensor is preferably disposed in the passenger compartment of the vehicle. In the event of a dangerously high gas concentration, a fan and/or power window control is triggered via a control unit in such a way that the fastest possible air exchange in the passenger compartment of the vehicle results.
