    Abstract: The invention provides apparatuses and associated methods of manufacture for fuel cell systems designed for modular application. As an example, a fuel cell system is provided that includes an enclosure housing a fuel cell stack, a power conditioning circuit, and a control circuit. The power conditioning circuit has a first input connector electrically coupled to the fuel cell stack. The power conditioning circuit is adapted to convert a direct current flow from the fuel cell stack to a conditioned alternating current flow having a predetermined voltage (e.g., 120 volts). The conditioned current flow is provided to an outlet connector of the power conditioning circuit located along a first portion of the enclosure. The power conditioning circuit further includes a second input connector located along a second portion of the enclosure. The second input connector is adapted to receive an external current flow.
