Problems solved by technology

Due to the disadvantages of poor thermal and chemical stability of the anionic membrane, it is limited by high temperature.
In addition, adding additional electrolytes (such as sodium hydroxide, potassium hydroxide, etc.) will reduce the theoretical energy density of the system, increase the complexity of the system and input costs, etc.
In addition, while the traditional chlor-alkali industry prepares caustic soda, it needs to consume clean electric energy, and it will pollute the environment in the process

Embodiment Construction

[0018] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0019] see figure 1 , the present invention comprises an anode plate 6, a cathode plate 7 and a cation-exchange membrane 1 that separates it into an anode cavity and a cathode cavity for conducting sodium ions. Water, the oxidant uses pure oxygen or oxygen from the air, and the anode chamber side of the cation exchange membrane 1 that conducts sodium ions is provided with an anode catalytic layer 4 and an anode diffusion layer 2 in sequence from the inside to the outside, and the cation exchange membrane that conducts sodium ions The cathode chamber side of the membrane 1 is provided with a cathode catalytic layer 5 and a cathode diffusion layer 3 sequentially from the inside to the outside. The anode and cathode diffusion layers 2 and 3 use carbon paper with a microporous layer as a supporting material, and the catalyst The sl...

Abstract

The invention discloses a high temperature direct formate fuel cell (Na-DFFC) with electricity and alkali salt co-production belonging to the field of fuel cells, including a non-platinum cathode and a non-platinum anode using polytetrafluoroethylene (PTFE) as a binder, and a cationic membrane of a sodium ion form. Compared with traditional formate fuel cells, additional electrolyte (such as sodium hydroxide) is not required to be added to the Na-DFFC anode, so that the energy density of the system is improved, and the design complexity and cost of the system are reduced. In addition, by replacing the traditional anionic membrane with the cationic membrane of a sodium ion form, the shortcomings of poor thermal stability and poor chemical stability of the anionic membrane are overcome. At the same time, by replacing the traditional ion exchange resin binder with the polytetrafluoroethylene (PTFE), the fuel cell compared with the traditional fuel cell is more resistant to high temperature. In addition, important chemical raw materials including sodium hydroxide and sodium carbonate are produced along with electricity outputting by the Na-DFFC, that is, forming the so-called electricity and alkali salt co-production, so that the range of applications is very wide.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a high-temperature electric alkali salt co-production direct formate fuel cell. Background technique [0002] In recent years, the fossil energy mainly oil, coal and natural gas that supported the rapid development of human civilization in the 20th century has experienced an unprecedented crisis. In addition to the continuous decline in its reserves, what is more serious is that scientific research has found that fossil energy After the carbon dioxide gas produced is emitted into the atmosphere as a greenhouse effect gas, it has artificially caused global warming, which has aroused people's widespread concern and thinking about the power source of future social development. The energy strategies of many countries have an obvious policy orientation—to encourage the development of new energy sources. This is not only caused by the high price pressure of traditional energy products such as...
