Japan's invention water driver can run 80 kilometers in 1 litre of water

Reuters recently reported that a Japanese company has invented a new type of environmentally friendly electric vehicle that uses water as its fuel. This type of car only requires 1 litre of water to run for an hour at 80 km per hour, and rain, river water or sea water, any water can be. "As long as you have a bottle of water in your hand, it will be able to run," said Kiyoshi hirasawa, chief executive of genepax, to Tokyo TV.

According to Tokyo television, when water is injected into a tank at the rear of a vehicle, the generator in it will break down the water and use it to generate electricity.
It is unknown whether the car will be displayed. Genepax said they are applying for a patent for it and hope to cooperate with Japanese automakers in the future.

Genepax explains that they use a new fuel battery system technology called "Water Energy System (WES)" that uses water to act as fuel without emissions of carbon dioxide. The system supplies external water and air to the fuel cell and air electrode separately to generate electricity. The company said at a press conference held in Osaka Hall on June 12 that the basic power generation principle of the system is similar to that of a common hydrogen fuel cell. When water is injected into the tank at the rear of the vehicle, the generator in it will break down the water and use it to generate electricity.
According to the company, the main feature of this system is the use of a technology called membrane electrode assembly, MEA, water can be decomposed into hydrogen and oxygen through chemical reactions, thereby driving the vehicle forward. Although the company did not disclose detailed technical details, it was able to use this technology to allow the MEA to generate hydrogen from aquatic production, Kiyoshi hirasawa said. This chemical process is similar to the hydrogen produced by the reaction of hydrogen metal and water, but they say this technology is the most advanced so far and is more efficient than the existing technology, with lower costs, it can produce longer periods of hydrogen in aquatic products.

With this new technology, the fuel cell can produce hydrogen only from water and air, so it can no longer be equipped with a tank for storing high-pressure hydrogen. Moreover, the membrane electrode group does not require special catalysts, but only some rare metals such as platinum are required, which also exists in the existing system.
Unlike direct methanol fuel cells (DMFC) that use methanol as fuel, this new system does not emit carbon dioxide. In addition, it may have a longer life, because carbon monoxide in traditional fuel cells can lead to catalyst poisoning and lead to its catalytic performance being weakened. On the contrary, the fuel electrode of the new system will not produce carbon monoxide, this can prolong the service life. It is estimated that its life can reach more than one year. The company plans to collect more data about the product's life cycle.
At a press conference, the company presented a 120-watt fuel cell stack with an output power and a 300-watt fuel cell system. In the demonstration, the 120 Watt fuel cell heap was first supplied with water from a pump driven by a dry electric pool, and it was able to run even when the pump was shut down. At this time, the fuel cell stack voltage is 25-30 volts. The Fuel Cell Stack is composed of 40 batteries. The output power of each battery is 3 watts or more, the voltage is about 0.5-0.7 volts, and the current is about 6-7 amps. Because the battery has a reaction area of 10x10 cm, its power density may be less than 30 MW per square centimeter.

At the same time, the 300 watt fuel cell system is also activated after water and air are added through the pump. During the demonstration, genepax used this system to enable television and lighting devices with lead-acid rechargeable batteries. In addition, the 300 watt system was installed in the suitcase of the compact electric car "Reva" produced by takeoka mini car manufacturing company, and the electric car was indeed started under the drive of the system.
Genepax initially planned to produce a 500-watt system, but did not produce any special material for MEA in time, and finally only produced the 300-watt system. They are applying for patents for them and hope to cooperate with Japanese automakers in the future. In the future, the company plans to supply a 1 KW-level power generation system for electric vehicles and residential use. In addition to driving cars with this system, the company also expects to use it as a generator to charge the battery of electric vehicles.

Although the engine used by the car is currently at a cost of 18522 yen (about USD), the company said that if mass production can be achieved, the cost can be reduced to 0.5 million yen (about 32 thousand RMB ). If the cost falls below that level, the company believes their fuel cell systems can rival solar cell systems.
