A fuel cell arrangement (10) and its operation are described. This fuel cell arrangement (10) comprises one or more fuel cells (1) to which a combustible gas or a cathode gas is fed and which supply an electric power Pext to an external consuming device (2). One or more internal electrical consuming devices (3) can optionally be switched on and off by means of a control device (5) as a function of the operating condition of the fuel cell arrangement (10). Excessive heat is removed from the fuel cell arrangement by means of a cooling device (4). According to the invention, a portion of the electric power PBZ generated by the fuel cells (1) is converted at the internal electrical consuming devices (3) during the operation of the fuel cell arrangement (10). When the electric power Pext supplied to the external electrical consuming device (2) increases or decreases, the electric power Pint converted at the internal electrical consuming devices (3) is reduced or increased inversely in the sense of making the electric power PBZ generated by the fuel cells (1) uniform. This is carried out by the control device (5) of the fuel cell arrangement (10).
