Abstract
The current invention is a fuel cell controller that includes a first control loop, where the first control loop is disposed to adjust a fuel cell current to regulate a hydrogen output pressure from the fuel cell to a pressure target valve, and further includes a second control loop disposed to adjust a hydrogen flow rate from a hydrogen generator to match a DC/DC power output to a power target value.
