What is a Hydrogen Fuel Cell?

A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, the emitted electrons reach the cathode through an external load.

Using elements

Dry batteries and accumulators are energy storage devices that store electrical energy and release it when needed; hydrogen fuel cells are, strictly speaking, a power generation device. Like a power plant, it is a chemical that directly converts chemical energy into electrical energy. Chemical power plant. In addition, the electrodes of hydrogen fuel cells are made of specially made porous materials. This is a key technology of hydrogen fuel cells. It not only provides a large contact surface for gases and electrolytes, but also catalyzes the battery's chemical reaction. .

According to the International Energy Storage Summit, the application of hydrogen fuel cells in developed countries is accelerating as a zero emission clean energy source. Japan will build 100 hydrogen refueling stations by 2015 and 13 have been completed. The European Union has recently approved the addition of fuel cell bus projects; the batch production model of the Hyundai ix35 fuel cell vehicle has been offline in March 2012, and it is planned that Mass production from the beginning. This shows that the fuel cell has truly moved from the laboratory to industrialization, and compared with lithium batteries, it has the advantage of zero pollution.

The U.S. Department of Energy said to the public that South Korean automakers Hyundai and German automakers

Commercial Mercedes-Benz, Japanese auto maker Nissan and Toyota Motor have reached an agreement with the department to prepare the first round of hydrogen-powered vehicles. This public-private partnership model will focus on the construction of hydrogen energy infrastructure, and will be named H2USA.

Hyundai Motor held a mass production ceremony for hydrogen fuel cell electric vehicles at the Ulsan plant. It will officially produce the Tucson ix hydrogen fuel cell electric vehicles from the end of this month.

At the European level, the Netherlands, Denmark, Sweden, France, the United Kingdom, and Germany have reached an agreement to jointly develop and promote hydrogen energy vehicles. Countries will jointly build a European hydrogen facility network and coordinate energy transmission.

The British government has proposed that it will vigorously develop hydrogen fuel cell vehicles. It plans to have 1.6 million hydrogen fuel cell vehicles in the UK by 2030 and bring its market share to 30% -50% by 2050.

China's first hydrogen fuel cell electric locomotive finally developed successfully after four years and can be used in industrial fields, such as mining tractors. In addition, during the 2008 Olympic Games, 20 hydrogen fuel cell cars independently developed by China were put into operation, and Tongji University participated in the development of the first batch of fuel cell vehicles that obtained national road permits. ^[5]

On June 30, 2010, Shandong Dongyue Group announced to the world that China's self-developed chlor-alkali use of perfluoro ion membranes and fuel cell membranes was domestically produced. After 8 years of scientific research, it broke the long-term monopoly of the technology in the United States and Japan. At the same time, "Dongyue" completed a 500-ton-a-year production unit for the manufacture of sulfonic resin ion membranes, the core material of fuel cells, and put into operation, solving a major bottleneck in the production of hydrogen fuel cells, and China became the world The third country has the technology and industrialization capabilities.

Japanese electronics parts maker Roma and Aqua Fairy and Kyoto University jointly developed a "high-energy hydrogen fuel cell." The battery can generate 5 watt-hours of power. Can be widely used in a variety of electronic equipment, including smart phones, or to provide backup power ^[6] supply in emergency situations.
