Definitions
- the present invention relates to operation control of a fuel cell that generates power by an electrochemical reaction between hydrogen and oxygen.
- a fuel cell has a configuration in which a hydrogen electrode and an oxygen electrode are arranged with an electrolyte interposed therebetween.
- a hydrogen-rich fuel gas is supplied to the hydrogen electrode and an oxidizing gas such as air is supplied to the oxygen electrode, hydrogen and oxygen in these gases react to generate water and generate power. This reaction occurs mainly at the oxygen electrode.
- flooding is more likely to occur during operating conditions with relatively low oxidizing gas flow rates, for example, when generating electricity at low current densities.
- Japanese Unexamined Patent Publication No. 63-111558 which is a Japanese patent, discloses a technique for suppressing flooding by intermittently increasing the flow rate of oxidizing gas.
- it is necessary to increase the pump power for supplying the oxidizing gas which has been a factor for reducing the energy efficiency of the fuel cell.
- the suppression of flooding due to the increase in the flow rate of the oxidizing gas has a low responsiveness because a certain delay time occurs after the pump power is increased until the flow rate of the oxidizing gas increases. Due to such low response, the conventional technology requires that the oxidizing gas be increased quickly before flooding occurs.
- an object of the present invention is to provide a technique capable of avoiding flooding while suppressing a decrease in energy efficiency. Disclosure of the invention
- the fuel cell system of the present invention is directed to a fuel cell that generates power by an electrochemical reaction between hydrogen supplied to a hydrogen electrode and an oxidizing gas supplied to an oxygen electrode.
- a solid polymer type using a solid polymer membrane such as Naphion (registered trademark) as an electrolyte is preferable.
- the fuel cell system includes an outlet pressure adjusting mechanism that adjusts the outlet pressure of the oxygen electrode, and a pressure controller that controls the outlet pressure adjusting mechanism.
- the pressure control unit controls the outlet pressure adjusting mechanism so as to intermittently reduce the outlet pressure from the standard pressure to be maintained during normal operation.
- As the outlet pressure adjusting mechanism for example, a pressure adjusting valve provided on the outlet side of the oxygen electrode, a pressurizing pump for supplying an oxidizing gas, and the like correspond.
- the present invention By lowering the outlet pressure, the water in the oxygen electrode is drained because the outlet pressure of the oxygen electrode becomes transiently lower than the inlet pressure.
- flooding can be suppressed while maintaining the humidity required for the electrolyte membrane.
- the power required for lowering the outlet pressure is smaller than the power required for increasing the flow rate of the oxygen-oxidizing gas, and therefore, according to the present invention, it is possible to suppress energy loss due to drainage.
- the present invention since the rate of change of the pressure is relatively high, the present invention has an advantage that the responsiveness of the wastewater treatment can be improved.
- the flow rate control of the oxidizing gas may be performed together with the control of the outlet pressure.
- the fuel cell system of the present invention includes a flow rate adjusting mechanism that adjusts the flow rate of the oxidizing gas supplied to the oxygen electrode, and increases the flow rate under a predetermined condition when the pressure decreases. May be controlled.
- the flow rate adjusting mechanism corresponds to, for example, a pressurizing pump for supplying an oxidizing gas, a flow rate adjusting valve provided in an oxidizing gas supply system, or the like. By increasing the flow rate in this way, more efficient drainage can be realized.
- the "predetermined conditions" for increasing the flow rate can be variously set. For example, the flow rate may be increased each time the pressure is reduced, or the flow rate may be increased once every several times.
- the flow rate may be increased.
- a relatively large power is required to increase the flow rate. Therefore, from the viewpoint of energy efficiency, it is preferable to preferentially use a decrease in pressure for drainage rather than an increase in flow rate.
- various settings can be made for the timing at which drainage control such as pressure reduction is performed.
- the drainage control may be repeatedly performed at a preset cycle, or the necessity of drainage control may be determined based on the operating state of the fuel cell system.
- the amount of water accumulated in the oxygen electrode or its fluctuation may be estimated, and whether or not drainage control is necessary may be determined based on the result.
- the fuel cell system can execute drainage control when it is determined based on this estimation that the accumulated amount or its fluctuation exceeds a predetermined allowable value. In this way, unnecessary drainage control can be suppressed, and energy efficiency can be improved.
- Fluctuations in the amount of accumulation can be determined, for example, by the difference between the amount of water generated and the amount of water that can be drained. In addition, by integrating the fluctuations obtained in this way over time, the amount of accumulated water can be estimated.
- the amount of production used in this estimation is a function of the amount of power generation and the time of power generation
- the amount of drainable water is a function of the flow rate of the oxidizing gas and the pressure or temperature. Pressure and temperature are parameters that specify the amount of water vapor that can be included as saturated water vapor in the exhaust gas from the oxygen electrode.
- the amount of generation and the amount of drainable water can be obtained by storing in advance a map that gives the amount of water generation and the amount of water drainable for these parameters.
- the allowable value for judging the necessity of drainage control is more than the amount of storage that is determined to cause flooding. Can be set to a lower range.
- the fluctuation of the accumulation amount for example, by setting 0 as an allowable value, when the accumulation amount increases, it may be determined that drainage control is necessary.
- These allowable values may be fixed values or may be varied according to the required power generation amount.
- the outlet pressure is once increased from the standard pressure and then decreased below the standard pressure.
- the differential pressure between the inlet pressure and the outlet pressure can be increased, and efficient drainage can be realized.
- the inlet pressure may decrease over time, which may lead to a shortage of oxidizing gas supply.
- a restriction may be imposed on the reduction of the outlet pressure in the present invention so that the reduction is performed under the restriction that the inlet pressure of the oxygen electrode is maintained at a predetermined value or more.
- the inlet pressure is maintained at a predetermined value at which the appropriate supply of the oxidizing gas can be realized, so that the fuel cell can be operated stably.
- Such control can be realized, for example, by prohibiting a decrease in outlet pressure when it is determined that the inlet pressure becomes lower than a predetermined value.
- the outlet pressure adjusting mechanism can be provided at various locations.
- a pressure adjusting valve provided in an exhaust pipe that exhausts from an oxygen electrode of a fuel cell may be used as an outlet pressure adjusting mechanism.
