What types of material can a fuel cell be made of?
There are 3 main types of a Fuel Cell. 1. Hydrogen Fuel Cell. This is the main one people use nowadays. 2. Solid Oxide Fuel Cell. 3. Alkaline Fuel cell. Made from Alkaline metals.
Which statement best describes the use of a catalyst in a fuel cell?
A catalyst in a fuel cell speeds up the chemical reactions that convert fuel and oxygen into electricity, without being consumed in the process. It lowers the activation energy required for the reactions to occur, increasing the efficiency of the fuel cell.
What are the cathode and anode in a fuel cell made from?
The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.
What is the green colored catalyst in a plant cell called?
The green colored catalyst in a plant cell is called chlorophyll. It plays a crucial role in photosynthesis, capturing light energy and converting it into chemical energy to fuel the plant's metabolic processes.
What has the author Joseph Singer written?
Joseph Singer has written: 'Evaluation parameters for the alkaline fuel cell oxygen electrode' -- subject(s): Electrodes, Fuel cells, Electrochemistry
What is cat crack gasoline?
Catalytic cracked gasoline is gasoline made with a catalyst that speeds up the cracking reaction in the refinery. This shortens the time used to make gasoline (and other products) from crude oil. Catalysts used is zeolite, aluminum hydrosilicate, bauxite,silica-alumina etc.
What type of fuel is used in model rocketry?
There are two main types of fuel: solid fuel and liquid fuel. Rocket fuel most use both a fuel and an oxidizer. The solid fuel in most modern rockets uses aluminum powder as fuel, ammonium perchlorate as an oxidizer, and iron oxide as a catalyst. Liquid fuel uses liquid hydrogen as fuel and liquid oxygen as an oxidizer.
Is aluminum fossil fuel?
No, aluminum is not a fossil fuel. It is a metal to which different alloys are added for specific applications.
What fuel is used in a fuel cell automobile engine?
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
What main part of a fuel cell is made out of a polymer?
The membrane electrode assembly (MEA) is the main part of a fuel cell that is made out of a polymer. It consists of a polymer electrolyte membrane sandwiched between two catalyst-coated electrodes. The polymer membrane allows for the movement of ions while blocking the passage of gases.
How is a fuel cell different from a typical cell?
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
Is Aluminum a fossil fuel?
No, aluminum is not a fossil fuel. It is a metal to which different alloys are added for specific applications.
