Abstract

The invention discloses a water-cooled seal fuel cell stack. The fuel cell stack is encapsulated in a housing, and comprises a plurality of single cells connected in series and stacked; each cell comprises a membrane electrode, a hydrogen plate and an oxygen plate; the hydrogen plate and the oxygen plate are respectively arranged on two sides of the membrane electrode; an anode sealing plate tightly presses one end of the fuel cell stack; a cathode sealing plate tightly presses the other end of the fuel cell stack; a pipe inlet and a pipe outlet are formed in the housing; the pipe inlet is provided with a hydrogen input pipeline and an air input pipeline which are led to the fuel cell stack; hydrogen required by fuel cell stack reaction flows in from a hydrogen pipeline, and oxygen required flows in from an air pipeline; the pipe inlet is provided with a cooling tank led to the fuel cell stack, and a cooling water pipeline for providing cooling water for the fuel cell stack; and a hydrogen output pipeline, an air output pipeline and a cooling water drain pipeline, connected with the fuel cell stack, are connected to the exterior of the housing through a pipe outlet. The fuel cell stack is influenced a little by the environmental temperature, the pollution of air impurities on the membrane electrode can be reduced, the overall uniformity of the fuel cell stack is good, and the service life of the fuel cell stack is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fuel cells and relates to a water-cooled sealed fuel cell stack. Background technique [0002] The fuel cell is to directly convert the chemical energy stored in the fuel and the oxidant into electric energy in an efficient and environmentally friendly way by chemically reacting the fuel in the electrolyte. The fuel does not undergo combustion and does not have the complex energy conversion process of the internal combustion engine. The efficiency is the highest among all power generation methods at present. Since it has no moving parts and no combustion, it has low noise and small infrared signature. [0003] The core of the fuel cell power generation device is the electric stack, and its performance directly determines the performance of the entire battery. The fuel cell stack is composed of single cells stacked in series. Whether the temperature of each single cell is uniform affects the overall perf...
