Assignee: ROBERT BOSCH GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A fuel cell stack comprising:
a control device being configured to actuate the fuel cell stack in accordance with a desired predetermined current (IV), to measure a resulting voltage (U), and to compare the resulting voltage (U) with a reference voltage (UR), the predeteiztiined current (IV) being dependent on the reference voltage (UR) via a sum of at least two exponential functions whose argument in each case contains the reference voltage (UR), and
the control device being configured to ascertain the reference voltage (UR) by approximately reversing a correlation between the predetermined current (IV) and the reference voltage (UR) using an iterative approximation algorithm.
