Fuel Tank Vs Fuel Cell: What Sets Them Apart From One Another?

You've probably heard of a fuel tank; after all, your car has one! The fuel cells, on the other hand, are a near relative of the gasoline tank. However, both a fuel tank and a fuel cell are intended to hold fuel. Fuel tanks and fuel cells have several differences. In this article, we will look into the various differences between a fuel tank and a fuel cell.


In this article:

What Is A Fuel Tank?

In an automobile, truck, or SUV, the fuel is filled in a fuel tank. This fuel can be any substance used to power an engine, including ethanol, diesel fuel, and gasoline. 


A  fuel tank comprises stamped steel or molded plastic and is situated underneath the back of the car, though the manufacturer may choose to place it wherever else on the car. 


Fuel tanks provide fuel to an engine through a fuel pump so that it can run. In general, fuel tanks are constructed specifically to fit a specific vehicle’s year, make, and model. There are several designs of fuel tanks that allow them to wrap or mold around other parts of the vehicle. This not only enables the addition of more fuel but also improves the weight distribution of the fuel inside the car.

What Are The Benefits Of A Fuel Tank?

A fuel tank of your vehicle has the following benefits:


Better Fuel storage

A fuel tank holds a specific amount of fuel while preventing leaks and reducing evaporative emissions.


Filling

A fuel tank provides a secure, spark-free filling procedure for fuel to be filled in the tank.


Custom Fitting

A fuel tank is custom-fitted for your vehicle with the specific make, year, and model.



When To Replace A Fuel Tank?

The fuel tank's construction is robust, and therefore, fuel tank malfunctions are uncommon. Despite this, drivers must cope with premature fuel tank replacement or maintenance. It is advised to get a replacement fuel tank if one of the following damages is discovered:


Fuel Tank Wear

The aggressive actions of the fuel cause natural wear on the tank walls. This is usually the case with metal fuel tank containers.


A Hole In The Wall Of Fuel Tank

A hole occurs in the wall of a fuel tank when you drive irresponsibly on a rough road. This is common while driving over rough terrain with a lot of sharp stones poking out of the ground.


Dents In The Fuel Tank

Such damage is expected when the bottom of your car hits the ground. However, this can occur when the ventilation system fails (A vacuum develops in the fuel tank, yet the fuel pump continues to function).


Corrosion Of Fuel Tank

The fuel tank's walls become thin in areas of deterioration. When the damaged area cannot cope with the vapor pressure or vacuum, a crack is formed and fuel begins to seep in. In some cases, corrosion damages the top of the product, which is not easy to diagnose. But in the event of such damage, there will be a constant smell of gasoline near the car.


Fuel Tank Container Depressurization At The Soldering Location

This usually occurs as a result of a manufacturing defect, such as a poorly welded seam or improper anti-corrosion treatment.


Broken Thread

This happens to owe to manufacturing defects at the filler neck, but very rarely. The thread breaks off at the location where the fuel level sensor and fuel pump are installed. Because this section of the car is seldom repaired, the bolts corrode with age. When a mechanic attempts to unscrew them to replace a broken element, the stud or nut thread breaks.

The Fuel Seals Wear

Fuel seals are located where the fuel pump construction and level sensor reside. The fuel seal which is made up of rubber substances deteriorates over time. It is advised to replace the fuel rubber seal while maintaining the fuel pump as it is attached to it.



What Is A Fuel Cell?

Fuel cells are similar to fuel tanks, they hold fuel that is supplied to the engine. A fuel cell is a fuel tank that is specifically developed and manufactured for racing vehicles. Fuel cells are more resistant to impact than fuel tanks. They are made up of steel, aluminum, and high-strength plastic. Fuel cells are a "Universal" fit and are rectangular in shape, put in the vehicle's trunk. The fuel cell is reinforced with tougher metal and has numerous other safety mechanisms to prevent fluid leakage or puncture.

What Are The Benefits Of A Fuel Cell?

The benefits of having a fuel cell are:


Burst strength

Fuel cells have greater burst strength than that of a fuel tank. The burst strength is the measure of the strength of a material in pounds per square inch. As fuel cells are made of high-quality materials such as steel, aluminum, and high-strength plastic they have high burst strength.


Prevents Spilling

Fuel cells are designed with a non-vented cap with a tip-over valve to prevent the spilling of the fuel on the road when the racing vehicle is rolling over.


Multiple Sizes

As fuel cells are a universal fit, you have the option of selecting the size of your fuel tank.

What Are The Differences Between A Fuel Tank & A Fuel Cell?

Fuel is stored in both fuel tanks and fuel cells. That is the only similarity between them. There are several differences between a fuel tank and a fuel cell and those are:

FAQ
Burst strength is the main distinction between a fuel cell and a fuel tank. Fuel cells have a very high burst strength because they are primarily made for racing, which prevents fuel from pouring out in the event of an accident or rollover. While fuel tanks have a very low burst strength, which causes an easy spillage of fuel during accidents or rollovers.
A car's fuel tank has a capacity of 45 liters to 65 liters. However, the size of the tank is reduced in Nano vehicles compared to SUVs and trucks.
It is advised to clean your fuel tank whenever you replace your fuel tank pump.
A fuel tank can be repaired if it has become old. A good weld can last for several years, extending the life of your fuel tank.
