A microgrid system includes first and second DC power sources electrically connected to respective first and second DC electrical power busses, a first uninterruptable power module electrically connected to the first DC electrical power bus and configured to be connected to an alternating current (AC) load, a second uninterruptable power module electrically connected to the second DC electrical power bus and configured to be connected to the AC load, a first bi-directional AC/DC inverter having a DC end and an AC end, where the first DC electrical power bus is connected to the DC end of the first bi-directional AC/DC inverter, a second bi-directional AC/DC inverter having DC and AC ends, where the second DC electrical power bus is connected to the DC end of the second bi-directional AC/DC inverter, and an AC electrical power bus electrically connected to the first and second bi-directional AC/DC inverters at their AC ends.

Methods of fuel cell operation with bi-directional inverters

During a steady-state mode of operating a fuel cell system, a system power is generated by fuel cells and is provided via a steady-state bus to a first BOP load, to a second BOP load, and to a power grid via a transformer and via at least one of a bi-directional first inverter or a bi-directional second inverter. During startup mode operation of the fuel cell system, external power from the power grid is provided via the transformer, via one of the first or second inverters and via a startup bus to the first BOP load and the second BOP load.

Fault tolerant electrical architecture for fuel cell systems

A sorbent bed assembly of a fuel cell system, including a first sorbent bed, a second sorbent bed and at least one third sorbent bed, the second sorbent bed disposed between the first sorbent bed and the at least one third sorbent bed, a cover plate on the plurality of sorbent beds and configured to connect the sorbent beds to one another, a fuel inlet connector on the cover plate and configured to receive a fuel, a manifold having a first fluid conduit configured to transport fuel between the first sorbent bed and at least one third sorbent bed, and a second fluid conduit configured to transport fuel between at least one third sorbent bed and the second sorbent bed, and a fuel outlet connector on the cover plate and configured to receive fuel that has passed through each of the sorbent beds.
