Abstract

The invention discloses a fuel cell. The fuel cell comprises a first electrode and a second electrode, wherein the first electrode is connected with the second electrode through a cell part; the cell part is an aluminum shell, the exterior of which is coated with silver; a middle diaphragm is arranged in the aluminum shell to divide the aluminum shell into an upper compartment and a lower compartment; a fuel solution is placed in the upper compartment while sodium borohydride is placed in the lower compartment; the fuel solution is ferric nitrate; a liquid filling opening is formed in the cell part; and a thread cap with a sealing strip is arranged on the liquid filling opening. The fuel cell is stable in power supply and long in duration; and in addition, an effect of prolonging the service time can be realized by re-adding the fuel solution.

Description

technical field [0001] The invention relates to a fuel cell and belongs to the field of new energy equipment. Background technique [0002] A fuel cell is a device that converts chemical energy directly into low-voltage DC electrical energy through an electrochemical reaction. Stable power generation of fuel cells requires sufficient supply of fuel and oxidant. At the same time, the heat generated by the electric stack and the water must be discharged from the electric stack in time. The oxidant is generally taken from the oxygen in the air, and the generated heat is taken out of the electric stack through the cooling medium and released. Complete heat exchange with the environment. [0003] The working voltage of a single cell of a fuel cell is low, about 0.7V. In order to meet various power supply requirements, a fuel cell stack is usually composed of multiple cells connected in series, and the inside of each cell is often caused by uneven distribution of gas, water, and ...
