Definitions
- a typical fuel cell system will include a number of sensors which will operate in association with an electronic control system having an embedded microcomputer, whereby a variety of inputs and outputs concerning the operating parameters of the fuel cell system can be observed and controlled. They would include, of course, the input of fuel gas and oxidizer gas, and the flow of electrolyte when it is circulated through the fuel cell stack. Moreover, those parameters and others such as the operating temperature of the fuel cell stack may be contingent upon a number of parameters including the terminal voltage and particularly the current being drawn from the fuel cell stack, as well as the pressure of fuel gas and oxidizer gas, and electrolyte, flowing through the fuel cell stack, the level of electrolyte in the electrolyte tank, and so on.
- the present invention is directed towards an alkaline fuel cell system in which, for example, the flow of oxidizer gas to the alkaline fuel cell stack will vary proportionately with the amount of electrical current drawn from the alkaline fuel cell stack. Even at zero load condition, however, there will be some minimal flow of oxidizer gas through the fuel cell stack.
- the electrolyte is returned from the alkaline fuel cell stack to the return column near the top thereof through a controllable back pressure valve which is a spring loaded relief valve by which the pressure head of the returned electrolyte at the exit from the fuel cell stack is maintained above the ambient atmospheric pressure.
- the oxidizer gas Upon exit from the alkaline fuel cell stack 12, the oxidizer gas is directed to a cyclone separator 34 in which the bulk of the liquid, water and electrolyte that is carried by the oxidizer gas stream is removed, and thence to a demister 36. Any liquid which still remains in the oxidizer gas as it enters the demister 36 is returned to the separator 34 through line 74, and then it is returned back to the alkaline electrolyte tank 14. The spent oxidizer gas is exhausted from the alkaline fuel cell system at 38, where it is returned to the ambient atmosphere.
- the coefficients A and B are programmed into the memory of the electronic controller 50, and are selected so that value A determines the minimal amount of air flow when no current is being drawn from the alkaline fuel cell stack 12, and value B determines the stoichiometric excess of the air — which is typically 2 to 2.5 times the required stoichiometric value.
- the voltage VAIR is continually set to drive the oxidizer gas pump 16 when it is a volumetric, positive displacement pump.
- VAIR the operating voltage VAIR of the volumetric oxidizer gas pump 16 to preselected values such as VHICH or VMAX.
- FIG. 4 What is shown in Figure 4 is a novel arrangement whereby the height of the return column 44 may be kept at about the same height as the height of the fuel cell stack 12, thereby permitting easier packaging of the entire alkaline fuel cell system.
- a controllable back pressure valve which is a spring loaded relief valve 42 is provided.
- the precise details of the back pressure valve 42 are beyond the scope of the present invention, except that it will be understood that it is typically a spring loaded relief valve having fine controf over the spring pressure. This permits the maintenance of a positive pressure having the desired value, in the electrolyte, without the necessity for the increased height of the return column 44.
