摘要： A fuel cell system 1 comprises an electrochemical fuel cell stack 5 for generating electrical power to a service load 11. A load circuit 12 is switchably coupled to the fuel cell stack 5 for periodically receiving a discharge current from the fuel cell stack during an energy dissipation phase, such as an air stall operation for conditioning the fuel cell stack. A protection circuit 16 is coupled to the load circuit 12, configured to monitor a cumulative energy dissipation level during an energy dissipation phase and to abort the energy dissipation phase if the cumulative energy level reaches a predetermined threshold. In this way, lower specification resistor components can be used in the load circuit 5 for stack conditioning. A method of operating the fuel cell system and the protected electrical load device itself are also claimed.

摘要： A controller (81) in a fuel cell system (1A) operates a fuel cell (60) in a normal mode or in a special mode which is switched by the controller (81); in which in the normal mode, the fuel cell (60) is operated so as to satisfy at least one of a first operation condition and a second operation condition, the first operation condition being a condition in which an operation time of the fuel cell per unit period is equal to or shorter than a unit allowable operation time defined based on a total durable operation time of at least one of the fuel cell and the auxiliary device, the second operation condition being a condition in which the number of times of operation of the fuel cell per unit time is equal to or less than a unit allowable number of times of operation defined based on a total durable number of times of operation of at least one of the fuel cell and the auxiliary device, and in the special mode, the fuel cell (60) is operated without being limited by at least one of the first operation condition and the second operation condition.

摘要： The invention relates to a transport and testing trolley (1) for moving and conditioning and/or testing stacked assemblies of electrolyser and/or fuel cell components. The trolley allows to take stacks immediately at the end of an in-zone production, for example an inline production, to transport them directly to a conditioning and/or testing station and to implement conditioning and/or testing step(s) of said stacks directly on the trolley, without having to manipulate them before said steps.
