Classification: CPC H  Y | IPC H

Claim 6:
7. A non-transitory, computer-readable medium containing instructions that when executed by a computer cause the computer to control operation of an air compressor (5) in a fuel cell system (1) to
compress an air mass flow (4) that is fed to at least one fuel cell (3),
branch off, via a cooling air path (19), a cooling air mass flow (7) from a compressed air mass flow (6), wherein the cooling air path (19) has arranged in it a bimetallic matrix (25) and the bimetallic matrix (25) comprises bimetals which are arranged adjacent to one another and have different coefficients of thermal expansion, and
meter the cooling air mass flow (7) based on a controlled variable and a manipulated variable, wherein the controlled variable of a demand-dependent controller (20) is a temperature of cooling air at a cooling air outlet (24) of a turbomachine (15), wherein the manipulated variable of the controller (20) is a fluidic resistor (22) in the cooling air path (19), wherein a flow resistance of the fluidic resistor (22) changes as a function of the temperature of the cooling air at the cooling air outlet (24) of a turbomachine (15), and wherein the bimetallic matrix (25) forms the manipulated variable of the controller (20) and is supplied the cooling air at the cooling air outlet (24) of the turbomachine (15).
