Abstract

The present invention relates to a fuel cell system generating electric power using an electrochemical reaction between hydrogen and oxygen. The fuel cell system include power distributor selecting one of a system power source and a fuel cell stack as a power source generating power used for a variety of balance of plants (BOP) and a controller in accordance with an operational condition, and distribute power from the selected power source. The fuel cell system can stably distribute the power to the BOPs and the controller without generating the temporary contact point gap by switching the power source in a state where the system power and the stack power coexist.

Description

technical field [0001] The present invention relates to a fuel cell system that generates electricity using an electrochemical reaction between hydrogen and oxygen. More specifically, the present invention relates to a fuel cell system capable of selecting one of a system power source and a fuel cell stack as a power source for generating various balance of plants (BOP) and controllers according to operating conditions. power source and distributes power from the selected power source. Background technique [0002] A proton exchange membrane fuel cell (PEMFC) uses a proton exchange membrane having hydrogen ion exchange properties as an electrolyte membrane. PEMFCs generate electricity and heat through an electrochemical reaction between hydrogen-containing fuel gas and oxygen-containing air. PEMFC has fast start-up performance and can be designed in a small size. Therefore, PEMFCs are widely used in various applications such as portable power supplies, automotive power su...
