A single-phase fuel cell power conditioning system with minimized DC capacitor that achieves low-frequency ripple-free input current using a control-oriented power pulsation power decoupling strategy when an inverter load is connected. Without extra circuit components, the fuel cell system uses a smaller de bus capacitor (film capacitor) that replaces the bulky electrolytic capacitor.  The result is a reduced cost for fuel cell residential applications and distributed stationary fuel cell power generation systems.
