Problems solved by technology

The strength of the gas separation membrane is limited. If the pressure in the liquid storage chamber is high, or it is subjected to abnormal conditions such as impact, it is easy to damage the gas separation membrane, which will cause the separation function to fail or the liquid to leak.
This gas-liquid separator is not suitable for the separation of cathode products

Embodiment Construction

[0028] The present invention provides a gas-liquid separator for a portable fuel cell system. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0029] figure 1 It is a schematic flow chart of a portable fuel cell system involved in the present invention.

[0030]101 is a fuel cell stack, which directly converts the chemical energy stored in the fuel into electrical energy. 102 is an air pump, which delivers air to the stack cathode. 103 is a fan whose start and stop can be used to adjust the condensation efficiency of the condenser. 104 is a condenser, which is used to condense the water vapor at the outlet of the cathode. 105 is a water separator, which separates and collects condensed water, and dilutes the added high-concentration fuel or pure fuel at the same time. 106 is a carbon dioxide separator, used to separate the carbon diox...

Abstract

The invention relates to a gas-liquid separator for a portable fuel cell system. The gas-liquid separator comprises a gas-liquid separator cavity, a liquid suction soft pipe, a counterweight material,a fuel inlet, a fuel outlet, a gas-liquid mixture inlet, a gas outlet, a gas outlet pipe, a heat dissipator, a liquid level sensor, a baffle and other components, and has a symmetrical structure, wherein the liquid suction pipe is made of a flexible silicone rubber pipe capable of bending and having a certain strength, and naturally sags under the action of the counterweight material, the fuel inlet, the fuel outlet, the mixture inlet and the gas outlet pipe are respectively arranged on the centerline of the gas-liquid separator cavity, the gas-liquid mixing product of the fuel cell enters the gas-liquid separator cavity, and passes through the gas path formed by the baffle, and the water in the product is separated. Compared to the gas-liquid separator in the prior art, the gas-liquid separator of the present invention has the following advantages that the structure is simple, the water recovery does not require extra electric energy, and the gas-liquid separator can be used normallywithin an inclination angle range of +/-90 DEG.

Description

technical field [0001] The invention relates to a gas-liquid separator for a portable fuel cell system, in particular to the gas-liquid separator for separating and recovering water generated by the cathode of the portable fuel cell system. Background technique [0002] The fuel cell system is an electrochemical reaction device that directly converts the chemical energy stored in the fuel into electrical energy, in which the fuel cell fed with liquid fuel directly converts the chemical energy stored in the fuel (methanol, ethanol, etc.) An electrochemical reaction device for electrical energy. Compared with gaseous fuels, small molecule liquid fuels are easy to store and transport, have high energy conversion efficiency, and the oxidation reaction products are mainly water and carbon dioxide, which is an environmentally friendly green energy. [0003] Direct methanol fuel cell (DMFC) is currently the most widely studied type of fuel cell fed with liquid fuel. DMFC has the ...
