As the name suggests, hydrogen fuel power cells are batteries that use hydrogen as the raw material. The basic principle is the reverse reaction of electrolyzing water, which supplies hydrogen and oxygen to the cathode and anode respectively. Hydrogen diffuses outward through the cathode and reacts with the electrolyte, releasing electrons to reach the anode through external loads, thus generating electrical energy.

Regarding chemistry, which is taught by Chinese language teachers, it can be simply understood as combining hydrogen and oxygen to generate electricity and water, of which electricity is output for use by vehicles and water is discharged outside the vehicle.

In fact, hydrogen fuel cell is essentially a generator, but the raw material used is hydrogen. In fact, as early as the 1960s, hydrogen fuel cells had been successfully used in the aerospace field. The Apollo spacecraft that shuttles between space and Earth uses hydrogen fuel cells. So, hydrogen fuel power cells are not a product that has only emerged in recent years, but have only been used in automobiles in recent years.

There are two important advantages of hydrogen fuel power cells. The first is that the waste generated by its power generation is water, which will not cause pollution to the outside world when discharged from the vehicle; The second is the hydrogen fuel power cell, which directly converts chemical energy into electrical energy, with higher energy conversion efficiency than fuel engines.

Ix35FCV Structure Introduction

Although the appearance of the ix35FCV is not significantly different from that of the regular ix35, there are still differences in the internal structure of the body compared to the regular fuel version of the ix35.

The ix35FCV body can be divided into three parts, namely the hydrogen storage area at the rear, the battery and inverter in the middle, and the fuel power cell and powertrain at the front.

In the hydrogen storage area at the rear, there are two interconnected hydrogen storage tanks, whose shells are made of carbon fiber and aluminum, which balance lightweight and structural strength. The internal hydrogen storage pressure is 70Mpa, which is converted to a pressure of 10kg. Two hydrogen storage tanks can load a total of 5.64kg of liquid hydrogen.

Toyota has set the price of the Mirai at 7.236 million yen (approximately 374000 yuan, including tax), and the Japanese government also provides subsidies. After subsidies, the actual price is 5.2 million yen (approximately 269000 yuan). In February 2015, under pressure from Toyota Mirai, Hyundai announced a 43% reduction in the price of its Tucson fuel cell vehicle (also known as China's ix35) in South Korea, from the current 150 million won to 85 million won (approximately 480000 yuan). But even at a price of 480000 yuan, it is 28% more expensive than Toyota's Mirai.

Back then, Simida planned to skip the oil electric hybrid and directly develop fuel power cells, surpassing the island country in one fell swoop. However, the research and development was developed, but it was caught up with by Toyota, who was only two years late. It is estimated that Simida had a strong desire to die.
