Embodiment Construction

[0026] figure 1A device 100 for operating a fuel cell system with a fuel cell stack is schematically shown in FIG. The device 100 is configured to perform the methods described below. The device 100 comprises a first model 101 , a second model 102 and at least one third model 103 . The fuel cell system includes a fuel cell stack and a supply system. Said fuel cell system forms an overall system, which in this example is at least partially modeled with at least one third model 103 . In this example, at least one third model 103 is likewise a chemical or physical model described in particular by differential equations.

[0027] In this example the following four third models 103 are shown:

[0028] Model 103-1 for a portion of the overall system that is used for input and / or exhaust air.

[0029] Model 103-2 for the portion of the overall system used to add hydrogen from the tank system, vent purge gas from the anode path, vent the anode path moisture and circulate hydrogen...

Abstract

The invention relates to a device and a computer-implemented method for operating a fuel cell system. The method comprises specifying at least one control variable (u_req) for controlling the fuel cell system; determining a prediction (y_pred, dy_pred) of a variable (y_mes, dy) of the fuel cell system using a model (102) in accordance with the at least one control variable (u_req(t)) or in accordance with at least one control variable (u_act, u_pred) provided for the at least one control variable (ureq (t)); determining at least one parameter (P) of the model (102) as a function of the variable (y_mes, dy) and a prediction (y_pred, dy_pred) of the variable (y_mes, dy); according to the invention, at least one predetermined control variable is determined by means of the model (102) on the basis of an uncertainty measure (h(u_req)) of a prediction (y_pred, dy_pred) of the variable (y_mes, dy), the uncertainty measure (h(u_req)) satisfying a condition for the at least one predetermined control variable.

Description

technical field [0001] The present invention relates to an apparatus and a computer-implemented method for operating a fuel cell system. Background technique [0002] A fuel cell system is an overall system including a large number of subsystems. A fuel cell system includes one or more fuel cell stacks and a number of subsystems necessary to supply the one or more fuel cell stacks. [0003] A fuel cell stack usually does not have a single actuator, ie the fuel cell stack itself is a passive component or passive assembly by itself. [0004] While the individual subsystems of this overall system can be well described by physical models, it is difficult to model the dynamic interactions between the different subsystems and the fuel cell stack. For example, fuel cell stacks contain inertia such as thermal mass, water, or moisture that can change the dynamics of the overall system and can cause direction-dependent effects such as the difference between positive load jumps and l...
