MCFC, SOFC, PEMFC fuel cells, which has good development prospects? Urgent

This question is a bit bad.

These three fuel cells are not one purpose.

The prospects are all good, if the technology is ok.

MCFC and SOFC are both for large generators, most of which are 100 kilowatts or megawatts, and there are also small products of 1kw in the UK.

PEMFC is a small product, mainly a few hundred watts to tens of kilowatts, for car or household use, and the cost is very high.

At present, MCFC and SOFC seem to have a higher level of product maturity.

The new World Trade Center is equipped with MCFC.

Let's talk about it if you have questions.

SOFC is good.

All three have efficient cleaning characteristics, and the following judgment is only relative to the three.

MCFC is out of gas, high temperature, low transmission and low cost of output, and there is a liquid electrolyte, which is easy to lead to a decrease in reliability.

PEMFC has low temperature, low output and high cost, which is suitable for mobile power supply, the catalyst must use PT and other ***, and the fuel must use hydrogen, so the cost cannot be reduced, and there are potential safety hazards.

SOFC has high temperature and high output, and it can be used at a medium cost, from domestic combined heat and power to large-scale power plants or range extender engines for electric vehicles (Nissan is doing it). Fuel can be burned in a wide range of ways. The tubular type has been promoted in Japan, and the problem of better performing flat plate seals has yet to be solved (which seems to have been solved in the United States).

After large-scale production, there is a lot of room for cost reduction.

Ask the big boss to invest and support haha.

SOFC (Solid Oxide Fuel Cell): A high-efficiency power generation device that directly converts the chemical energy in fuels such as hydrogen, natural gas, etc., and oxidants into electrical energy without going through the combustion process.

Most fuel cells use hydrogen and oxygen in the air to generate electricity, and some use methane. Their common advantage is that they do not pollute the environment and are extensive. And the utilization rate of raw materials is relatively high.

The disadvantage is that most fuel cells use lye to conduct electricity, and once the lye leaks out, it will have serious consequences. Moreover, the technology in this area is not good enough and the utilization rate of raw materials is relatively low.

As for usability, some cars with gear buttons or some cities that need a high-quality environment will use it. After all, the cost is too high and not cost-effective.

Fuel cells are widely used, including military, space, and power plants, as well as motor vehicles, mobile devices, and homes. In the early days, fuel cell development focused on specialized applications such as military space and distributed power generation above kilowatts. The field of electric vehicles has become the main direction of fuel cell application, and a variety of automatic vehicles using fuel cells to generate electricity have appeared in the market.

In addition, the application of fuel cells to general consumer electronics through miniaturization technology is also one of the application development directions, with the advancement of technology, the future miniaturized fuel cells will be used to replace the existing lithium batteries or nickel-metal hydride batteries and other high-value products, as a power supply for portable electronic products such as laptops, radios, video recorders, cameras, etc. In the past 20 years, fuel cells have gone through several types of development stages, such as alkaline, phosphoric acid, molten carbonate and solid oxide, and the research and application of fuel cells are developing at a rapid pace. Of all fuel cells, alkaline fuel cells (AFCs) are the fastest-growing and provide power and drinking water for space missions, including the Space Shuttle; Proton exchange membrane fuel cells (PEMFC) have been widely used as transportation power and small power supply devices. Phosphoric acid fuel cell (PAFC) has entered the commercialization stage as a medium-sized power application, and is the first choice for civil fuel cells. The molten carbonate fuel cell (MCFC) has also completed the industrial pilot stage; As the most promising fuel cell in the field of power generation, solid oxide fuel cell (SOFC), which started late, is the preferred object for large-scale clean power stations in the future.

For many years, people have been trying to find energy utilization methods that have high energy efficiency and do not pollute the environment, and fuel cells are the ideal power generation technology. Fuel cells are very complex, involving many disciplines such as chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power system and automatic control, and have the advantages of high power generation efficiency and less environmental pollution.

Electric stationary fuel cells are used in commercial, industrial and residential and backup power sources.

Combined heat and power. Combined heat and power (CHP) fuel cell systems, including micro combined heat and power (microCHP) systems.

Fuel cell vehicles (FCEVs).
