Electric vehicles Vs Fuel Cell Vehicles

By -
Future Mobility

EVs and FCVs are developed and more developmental activities are taking place towards self-sustainable transportation at national and international level. the main scope is to reduce the carbon emission and produce less wastage on manufacturing. 

Electric Vehicles (EVs) are more widely adopted and offer better energy efficiency. They are suited for personal vehicles, especially in urban areas where charging infrastructure is available.

Fuel Cell Vehicles (FCVs) offer longer ranges and faster re-fuelling but are limited by hydrogen production and infrastructure challenges. FCVs may have a future in heavy-duty and long-range transportation if hydrogen technology improves.

Below are some of the key difference between electric vehicles and fuel cell vehicles or also called as hydrogen vehicles.

Category

Electric Vehicles (EVs)

Fuel Cell Vehicles (FCVs)

Power Source

Battery packs (mostly lithium-ion)

Hydrogen fuel cells, generating electricity from hydrogen

Energy Conversion

Electrical energy stored in the battery powers the electric motor directly.

Hydrogen reacts with oxygen in a fuel cell to produce electricity to power the motor.

Emissions

Zero tailpipe emissions (no exhaust, only electric operation).

Zero tailpipe emissions (water vapor is the only by-product).

Fuelling/Charging Time

Charging takes time; fast chargers can take 30 minutes to several hours.

Refueling hydrogen tanks takes 3–5 minutes, similar to gasoline refuelling.

Range

Typically between 150–400 miles, depending on battery capacity and vehicle efficiency.

Typically between 300–400 miles per hydrogen tank, depending on efficiency.

Fuelling Infrastructure

Charging stations are growing but still limited in some regions.

Hydrogen Refueling infrastructure is very limited, especially outside major cities.

Energy Efficiency

EVs are more energy-efficient, with about 60–70% of energy from the grid being used to move the vehicle.

FCVs are less efficient, with around 40–50% energy efficiency due to energy loss during hydrogen production, transport, and conversion.

Storage of Energy

Energy stored in lithium-ion or solid-state batteries.

Energy stored in compressed hydrogen tanks.

Weight

Batteries can be heavy, especially larger ones, affecting vehicle weight and performance.

Hydrogen tanks are generally lighter, but fuel cells add some weight.

Cost

EVs are becoming more affordable as battery technology advances. Prices are still high compared to conventional cars.

FCVs are currently expensive, primarily due to the high cost of hydrogen fuel cells and limited production.

Environmental Impact

Mining and production of lithium-ion batteries can have environmental effects. Recycling is necessary to minimize waste.

Hydrogen production (especially from natural gas) can generate carbon emissions unless produced from renewable sources.

Maintenance

EVs have fewer moving parts, leading to lower maintenance costs and higher reliability.

FCVs require more maintenance due to the complexity of the fuel cell system.

Performance

EVs offer instant torque and smooth acceleration, making them responsive and fun to drive.

FCVs offer good performance, but the power delivery is not as instantaneous as in EVs.

Noise

Quiet operation due to electric motors.

Quiet operation, though the fuel cell system may emit some noise.

Technology Maturity

Battery technology and EV systems are more mature, with a wide range of models available.

FCV technology is still emerging and less widespread, with limited models on the market.

Future Prospects

Growing adoption due to government incentives, improving battery technology, and increasing charging infrastructure.

Promising future, especially for long-range and heavy-duty vehicles, but dependent on hydrogen production and infrastructure development.

Examples

Tesla Model S, Nissan Leaf, Chevrolet Bolt

Toyota Mirai, Hyundai Nexo, Honda Clarity Fuel Cell

In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in collection

Solar panels installed on the roof with a capacity of 11.5 MW in Punjab state in India India’s solar mission which has kept at a target of 175 GW and the government is trying to keep its word to generate power from all kinds of Renewable Energy Resources. As it is focused on Solar, Wind and Biomass power generation technologies. We all know that a roof is the zero cost of land and uses the space for solar panel installation. There is no requirement of a special setup is installing the solar roof. Depending upon the roof size and shading and direction of the sunlight is considered for setting up the solar panels. But, most of them have small or medium roofs that can generate in kiloWatts (kW) or Megawatt (MW) scale. In Amritsar, there is an installation od 11.5 MW capacity of a solar power plant which is completely covered with solar roof which will benefit 8000 households was built by Radha Saomi Satsang Beas (RSSB), a religious organization in Punjab.

India is witnessing a new chapter in the growth of the renewable sector, mainly in the solar sector. Hence, any new breakthrough in the field of solar cells and solar power generation is beneficial for India. New technology is being developed in the University of Chicago within the confines of its chemistry laboratory by Professor “Luping Yu”. A new kind of solar panel was designed and manufactured which has a higher efficiency when compared with the currently running modules used for power generation. The given polymer solar cell consists of a new polymer, called "PID2". The new polymer improves the efficiency of electrical power generation by 15 per cent when added to a standard polymer-fullerene mixture. New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer a type of large molecule that forms plastics and other familiar materials which improved the efficiency of solar cells. The group also determined th
