Significant progress in aluminum fuel cell

the world's first fuel cell was invented by William grove in 1939. It has a history of 78 years. After these years of development, it has developed from a single aluminum fuel cell to a power supply with various practical values (the power supply system will be favored by more and more businesses), such as the stacked power station and vehicle mounted mobile power station of Deyang Dongshen New Energy Technology Co., Ltd. The anode of the battery is the aluminum plate with oxidation reaction, which is the electrode with electrons flowing out, and the cathode refers to the electrode with reduction reaction, which is the electrode with electrons flowing in

development of aluminum fuel cells in China

the large-scale research and development of aluminum fuel cells in the world began in the United States in the 1960s. In the 1970s, they focused on the research of batteries for power supply such as navigation beacon lights and mine lights; In the 1980s, aluminum power of Canada introduced the battery system made of aluminum alloy anode and effective air (oxygen) electrode to the market of portable power supply and standby power supply, which made a great contribution to the commercial application of aluminum fuel cells; In June 2014, foreign media reported that the power aluminum fuel device jointly developed by Alcoa and Israel's phenergy had a road test run on the vehicle, with a world record of 1600km. It is a milestone in the history of fuel cell development, and has made great contributions to the development of power aluminum fuel cells, making phenergy a leader in the world's aluminum fuel cells. The anode of this aluminum fuel cell system is composed of 50 aluminum plates, each of which has a mass of 500g and a total mass of 25kg. Each aluminum plate can provide power for electric vehicles to travel 32km. In February 2014, Alcoa and Fresnel king signed a cooperation agreement on the further development of aluminum fuel cells, and conducted a test drive of aluminum fuel cell electric vehicles at the formula one track in Montreal, Canada, in early June. It is planned to realize the mass production of aluminum fuel cells for electric vehicles in 2017 and introduce them to the world market

China's research and development of aluminum fuel cells began in the 1990s and has now become the world's largest R & D and production country of aluminum fuel cells, but there are still some gaps in research and development technology compared with the United States and Israel.

development trend of aluminum fuel cell

at present, power supply R & D units and production enterprises all over the world put their efforts into fuel cells, and the development of aluminum fuel cells is the top priority, because aluminum fuel cells have many comparable advantages: aluminum is rich in resources and reasonable in price. The manufacturing cost of aluminum fuel cells is about 500 yuan/kwh, which is 1/8 of the production cost of lithium-ion batteries of 4000 yuan/kwh; For cars, the operating cost is equivalent to or lower than that of fuel vehicles. Aluminum fuel cell vehicles consume about 3kg of aluminum, 5L of water and electrolyte for a hundred kilometers, and the operating cost is about 59 yuan. Generally, the fuel consumption of passenger cars is about 8l/100km, which is about 61 yuan calculated at 7.63 yuan/l; The endurance capacity is higher than that of lithium-ion battery. The specific energy of aluminum fuel cell can reach 350wh/kg-500wh/kg, which is three times that of lithium-ion battery 120wh-150wh/kg. Therefore, at the same quality, the power carried by aluminum fuel cell is three times that of lithium-ion battery, and the endurance mileage is three times that of lithium-ion battery; It is easy to replace. The aluminum fuel cell consumes aluminum and water. During operation, it only needs to replace the aluminum plate and add an appropriate amount of water, which is simple to operate; Green, the main by-product during the operation of aluminum fuel cell is al (OH) 3, which is not only harmless to the environment, but also recyclable, and made into nano-sized Al2O3 powder; It is absolutely safe and will not cause combustion and explosion
