All Flashcards
What is the effect of using hydrogen fuel cells on air quality?
Reduced air pollution due to water being the only byproduct.
What is the effect of high manufacturing costs on hydrogen fuel cell adoption?
It limits widespread adoption due to economic barriers.
What is the effect of hydrogen's flammability on fuel cell safety?
Requires stringent safety measures to prevent accidents.
What is the effect of hydrogen production methods on the environmental impact of fuel cells?
If hydrogen production relies on fossil fuels, the overall environmental benefit is reduced.
What is the effect of limited hydrogen availability on fuel cell use?
Restricts fuel cell use to areas with hydrogen infrastructure.
What is the effect of using PEM fuel cells in vehicles?
Reduces greenhouse gas emissions and air pollution compared to gasoline-powered vehicles.
What is the effect of quiet operation of hydrogen fuel cells?
Makes them suitable for use in residential areas and sensitive environments.
What is the effect of the need for infrastructure development for hydrogen distribution?
Increases the initial investment costs and logistical challenges.
What is the effect of high efficiency of hydrogen fuel cells?
Reduces energy waste and lowers operating costs.
What is the effect of quick start-up times of hydrogen fuel cells?
Makes them convenient for on-demand power generation.
What is the effect of using hydrogen fuel cells on air quality?
Improved air quality due to the absence of harmful emissions; only water is produced.
What is the effect of high manufacturing costs on hydrogen fuel cell adoption?
High costs hinder widespread adoption due to economic barriers.
What is the effect of limited hydrogen availability on fuel cell use?
Restricts fuel cell use due to lack of infrastructure and supply.
What is the effect of hydrogen flammability on fuel cell design?
Requires stringent safety measures to prevent accidents.
What is the effect of high efficiency of fuel cells on energy consumption?
Reduces energy waste and lowers overall energy consumption.
What is the effect of using fossil fuels to produce hydrogen?
Offsets some environmental benefits due to carbon emissions from hydrogen production.
What is the effect of quiet fuel cell operation on urban environments?
Reduces noise pollution, making them suitable for residential areas.
What is the effect of using PEM fuel cells in vehicles?
Reduces reliance on fossil fuels and lowers greenhouse gas emissions from transportation.
What is the effect of developing hydrogen fuel cell technology on job creation?
Stimulates economic growth by creating new jobs in manufacturing, research, and infrastructure.
What is the effect of water being the only byproduct of hydrogen fuel cells?
Minimizes environmental pollution and reduces the impact on ecosystems.
What is a hydrogen fuel cell?
A device that combines hydrogen and oxygen to produce electricity, water, and heat.
What is an anode?
The negative electrode in a fuel cell where hydrogen gas is fed.
What is a cathode?
The positive electrode in a fuel cell where oxygen from the air enters.
What is an electrolyte?
A substance in a fuel cell that allows ions to move between the anode and cathode.
What is a PEM fuel cell?
Proton Exchange Membrane fuel cell; commonly used in vehicles and portable devices.
What is cogeneration?
The simultaneous production of both heat and electricity.
Define 'fuel cell' efficiency.
The percentage of chemical energy in the fuel that is converted into usable electricity.
What is a byproduct?
A secondary product made in the manufacture or synthesis of something else.
Define 'renewable energy'.
Energy from a source that is not depleted when used, such as solar power or wind power.
Define 'emission'.
The production and discharge of something, especially gas or radiation.
