Abstract

A system and method for starting up a fuel cell system are disclosed. Briefly described, an embodiment for starting an electrochemical reaction between a fuel and an oxidant during a start-up process includes a fuel cell stack operable to output a nominal voltage during a normal operating condition and operable to output a reduced start-up voltage during the start-up process, and includes at least one balance of plant (BOP) device that supports operation of the fuel cell stack, operable at a nominal output when sourced by the fuel cell stack at the nominal voltage, and operable at a reduced output when sourced by the fuel cell stack at the reduced start-up voltage. BOP devices are loads contributing to the operation of the fuel cell system, such as control system, fuel or air supply systems, coolant system.

Description

technical field [0001] The present disclosure relates generally to electrical power systems, and more particularly to fuel cell stack start-up systems. Background technique [0002] Electrochemical fuel cells convert reactants (ie, fuel and oxidant fluid streams) to produce electrical power and reaction products. Electrochemical fuel cells generally use an electrolyte disposed between two electrodes, a cathode and an anode. An electrocatalyst disposed at the interface between the electrolyte and the electrode typically initiates the desired electrochemical reaction at the electrode. The location of the electrocatalyst collectively defines the electrochemically active region. [0003] One type of electrochemical fuel cell is a proton exchange membrane (PEM) fuel cell. PEM fuel cells generally use a membrane electrode assembly (MEA) that includes a solid polymer electrolyte or ion exchange membrane disposed between two electrodes. Each electrode typically includes a porous...
