Ever heard of hydrogen fuel cell vehicles? These cars are fascinating, as they are powered by hydrogen gas! That is quite different from typical cars that used gasoline to move. What makes hydrogen car so interesting is that instead of running on petrol or diesel, they run on hydrogen gas that generates electricity, which in turn drives the motor that powers the wheels. This means they work differently and are better for our planet.
While there are many great advantages of Hydrogen fuel cell cars! To start with, they do not emit harmful gases such as CO2 and CO into the atmosphere. Instead, they emit nothing but water vapor, which is clean and safe. This is very important since they help to reduce the air pollution. Also, these autos are extremely land-use efficient, able to operate long a long way on just a 50 percent tank. This is good for people who want to go out on road trips and not have to keep stopping for gas.
So how do hydrogen fuel cell cars work? The basic technology is a special device called a fuel cell. This device is a magic box, converting the hydrogen gas into electricity. Hydrogen gas flows into the fuel cell when the car is prepared for movement. In the fuel cell, hydrogen gas is separated via a chemical reaction into its components, which are small parts called protons and electrons. The electrons are transmitted through a circuit to turn on an electric motor — that’s what makes the wheels turn and the car go. At the same time, the protons combine with oxygen from the air to form water, which is expelled from the tailpipe as vapor that is not harmful to the environment. Using hydrogen gas as a fuel to generate energy is a smart trick!
As with everything in life, hydrogen fuel cell cars have their strengths and weaknesses. The one big advantage is that they are ecofriendly. The only thing they emit is vapor water, therefore, they do not contribute to the air pollution. This is great for our planet and helps keep the air clean for everyone. These vehicles are also incredibly fuel-efficient so they are capable of travelling a long distance on a single tank of hydrogen gas, making them very popular with long-distance commuters.
But there are also some negatives to doing so. A major issue is a lack of hydrogen gas filling stations. This can hinder people to do long trip since they may run out of fuel before being able to find a place to get refuel. Building the infrastructure necessary to produce and pipe hydrogen gas is also costly. More investment from governments and companies to make this actually work, in other words.
Hydrogen fuel cell cars contain the most important component, the fuel cell. The electrodes are the two special parts that make up the capacitor. One of them is positively charged, and that one is called the anode; the other is negatively charged, and that one is called the cathode. Between these two electrodes lies a layer called the electrolyte. At the anode, hydrogen gas enters and is split into protons and electrons. The protons can migrate across the electrolyte to the cathode, while the electrons must flow through an external circuit. The movement of electrons creates an electrical current that powers the car's motor, which drives it forward.
Hydrogen fuel cell vehicles have several beneficial results on our climatic system. They are very environmentally friendly, as they only produce pure water vapor, and do not contribute to air pollution. That means they help keep our air clean and healthy to breathe. Second, these vehicles reduce our consumption of fossil fuels (oil, gas) which are finite and will eventually run out over time. This is crucial for building a more sustainable future.
