What is a fuel cell control unit (FCCU)?

The fuel cell control unit (FCCU) is the central control unit for operation of the fuel-cell system – or “electrical power plant” – of an electric vehicle equipped with a fuel cell.

What is a fuel cell (FC) in power generation?

How to control a fuel cell and ultracapacitor hybrid energy system?

The power control technique of a fuel cell and ultracapacitor hybrid energy system using LQR–PI technique was evaluated in the current study. The control algorithm used a double-loop PI controller for the fuel cell boost converter and a voltage-mode LQR controller for the ultracapacitor bidirectional converter.

What is the operating range of FC unit?

The operating range of the FC unit is defined as 20–50 V by setting up the reference current range 50–250 A. If the current requirement is below than 50 A, the FC voltage will be at 50 V. It should be noted that from 50–250 A, FC will follow the V–I characteristics curve. This definition is for ensuring the FC operation in the ohmic region.

What is FC based hybrid system?

In FC-based hybrid systems, FC is used as main source of energy and other element like battery or UC is used as auxiliary source. The potential FC-based hybrid configurations are FC–battery–UC, FC–battery and FC–UC [ 5, 6 ]. In general, FC is a device that converts chemical energy of hydrogen into electricity through an electrochemical reaction.

How to control FC and UC in a hybrid system?

In this paper, a boost converter and a bidirectional half bridge converter are used for interfacing the FC and UC, respectively. The hybrid system is controlled through LQR–PI controller, where the FC and UC converters are controlled using a double-loop PI controller and a voltage-mode LQR controller, correspondingly.
