This report presents a complete package for bistable electromagnetic actuated microvalve. The function of the valve is to control the fuel delivery system in a fuel cell unit for power generation [1,2]. The microvalves were fabricated on top of a single wafer using 8 masking steps. The fabrication processes have a maximum processing temperature of 300 °C, providing potentially a CMOS compatible process. The valve arrays that compromise of 12 valves per 12 MM × 12 MM chip are built completely by surface micromachining. The chip is assembled into a package with fluidic connection parts. The parts were made from the stereo lithography (SLA) frame that was filled with PDMS. The PDMS also acts as a gasket to seal the microvalve from leaking. The fluidic tests show that the whole valve assembly can stand from leaks up to the pressure of 57.4 kPa.

Fuel Delivery

A fuel delivery system with dual recirculation lines is investigated in this paper, which can reuse the exhausted gas from the outlet of anode flow channel. In the automotive application, the fuel delivery system regulates the hydrogen pressure and flow rate from the tank to the anode flow channel that change dynamically with load. The control objectives of fuel cell stack require that a slight pressure difference between the anode and cathode be maintained to prevent the damage of the membrane. In addition, the unconsumed hydrogen is circulated to a supply line by the recirculation lines. The fuel delivery system analyzed in this paper consists of two supply lines and two recirculation lines. The supply line with a low pressure regulator accounts for the supply of fuel at relatively low load demands. The other supply line with a flow controller starts to provide additional fuel with controllable flow rate at high load demands. The recirculation line with an ejector allows for mixing the unconsumed hydrogen with the supplied fuel. The other recirculation line with a blower is used to improve the controllability of the recirculation flow rate. Analysis of the fuel delivery system with dual recirculation lines is carried out by modeling and simulating an integrated system, where the components are modeled involving the dynamic characteristics. The major components of fuel delivery and recirculation system are an ejector, a blower, and a pressure regulator. In addition, the linearization of the integrated system is expressed in the approach of state equations to form the control problem of the system. Then the linear controllers are designed based on the decentralized proportional and integral control, and the state feed-back control. The systems with the different controllers are simulated at different operating points to evaluate their tracking performance by comparing the dynamic response curves.
