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, the hydrogen and oxygen are supplied to the anode and the cathode respectively, the hydrogen diffuses outward through the anode and the electrolyte is reflected, and the electrons are released to reach the cathode through the external load.
And fuel cells are non-polluting to the environment. It is through electrochemical reactions, rather than combustion (gasoline, diesel) or energy storage (batteries) - the most typical traditional backup power scheme. Combustion releases pollutants like COx, NOx, SOx gases and dust. As mentioned above, fuel cells only produce water and heat. If hydrogen is produced through renewable sources (photovoltaic panels, wind power, etc.), the entire cycle is a process that completely eliminates the emission of harmful substances.
Advantages of hydrogen fuel cells
1, hydrogen fuel cell energy conversion rate is high, ordinary oil combustion generated energy conversion is only more than 30%, while hydrogen fuel cell energy conversion rate reached a staggering 80%. Consume less resources to get more energy, that is definitely a hydrogen fuel cell is more cost-effective.
2, compared with traditional fossil fuels, hydrogen fuel cells are electrochemical reactions, when providing energy, only water and heat will be generated. Traditional fossil fuels produce a variety of toxic and harmful gases and dusts, which is a great tool for polluting environmental health.
3, compared with other traditional batteries, hydrogen fuel cells are a power generation device, the traditional battery only has the function of storing electrical energy. Hydrogen fuel cells are like generators, directly converting chemical energy into electrical energy, which is much better in convenience than traditional batteries.

In fact, it is really not difficult to choose a big bull, as long as the method is right, the rest can be handed over to time to verify the line, review the record of this period of time: November 12 to share Yujing shares have accumulated a rise of 139%, there is a 122% increase in the Qiming information shared on November 26, and the three sheep horses that take everyone to do in December, by the end of December, 360% of the pockets are received, and the other big meat is not listed here, and the old splinters have the final say!
Here is a benefit for everyone, recently the author used his own way, combined with all aspects of the market hot themes and plates, from the market hundreds of hot stocks, sorted out and selected a low gold stock, want to return to the blood of friends, pay attention to me Gong. Zhong, Hao, (talk about investment stocks), these stocks shock sucked for several months, at present, with the market picking up, has begun to have the main funds involved, the rising channel has been opened, the trend is excellent, the outbreak is only a matter of time, conservative expected income of about 60 points, there is a large inflow of funds, the outbreak is imminent. Because of its confidentiality, investment is the realization of cognition. The importance of learning and communicating is beyond doubt, and everyone is welcome to come and disturb.
