The alkaline fuel cell and the alkaline fuel cell system include a film electrode complex, an anionic conductive electrolyte membrane, a first surface of the anionic conductive electrolyte membrane, and laminated in the first surface of the anionic conductive electrolyte membrane. The cathode on the surface opposing second surface; the first separator, at least the fuel receiving portion for receiving the fuel is laminated on the anode; the second partition plate, at least the oxidant receiving portion for receiving the oxidant is laminated in the cathode The alkaline aqueous solution supply unit, for contacting the alkaline aqueous solution only in contact with an anionic conductive electrolyte membrane in the membrane electrode composite. The peripheral system of the alkaline fuel cell (AFC) includes: air supply system, current collector, drainage system, cooling system, control system.1, gas supply system
Since CO in the KOH electrolyte can form a carbonate, the hydrogen and oxidant gas cannot contain high concentrations of CO2, which allows COs in actual use, and other side effects of other side effects on the battery should also be eliminated. Removing 0.03% of the CO in air: Chemical absorption, most of the practice is to pass the CO, gas three times by the absorbent. Commonly used absorbents have alkali lime, ethanolamine, and the like. Other CO2 preprocessing methods have a circular treatment using a molecular sieve or a PD-AG alloy film.
2, current collector
Like other types of fuel cells, current collects available single or bipolar. These two forms have advantages and disadvantages, which cannot be the characteristics of AFC. Electrochemical Energy Use the edge collection in the battery stack, Siemens use bipolar, and the American spacecraft AFC uses bipolar • Collection and edge collection.
3, drainage system
The product water produced by the fuel cell process must be continuously discharged from the battery stack to keep the concentration of KOH within a certain range. Drainage is also different in terms of different electrode types. One type is to carry moisture and cool the battery in the circulating electrolyte. The evaporation of water is carried out outside the battery stack. Another type is to exclude moisture by the reaction gas circulation.
4, cooling system
In hydrogen oxygen AFC. The heat is quite large. For hydrogen air AFC, electrochemical energy companies have two types of heat-insulating pathways, air and electrolytes. In both AFCs, both electrolytes must pass through the heat exchanger. If the electrolyte is fixed, it is necessary to install the cooling system in a certain number of batteries per spacer to take away the heat of the battery stack.
5, control system
The entire fuel cell system must be adjustable and controlled. There must be a control system that is fully propriminated by the start, operation and stop, etc. of the fuel cell, but also can perform certain interventions to prevent the fuel cells and their affiliate systems.
