Polymer electrolyte membrane fuel cells (PEMFCs) offer several advantages, including high efficiency and quick start-up times, making them suitable for various applications, such as transportation and portable power. They operate at relatively low temperatures (around 80°C), which allows for the use of lightweight materials and compact designs. Additionally, PEMFCs produce only water as a byproduct, contributing to their environmentally friendly profile. Their scalability and adaptability also make them ideal for both small and large-scale energy solutions.

Can Cement or solid paper work as Proton exchange membrane for MFC?
I'm planning to create a microbial fuel cell. Initially, im planning to use a Salt+agar mixture for my PEM but halfway into my project, i've been wondering if paper soak with NaCl solution or cement with NaCL could work. can anyone answer my question. thank you
Difference between Gel Battery And VRLA Battery?
A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Gel Cell, Absorbed Glass Mat (AGM), and Wet Cell are various versions of lead acid batteries. The Wet comes in two styles: serviceable, and maintenance free. Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium Wet Cell battery.
What is the maximum theoretical efficiency of an ammonia fuel cell?
The maximum theoretical efficiency of an ammonia fuel cell can be approximated using the Gibbs free energy change of the reaction. The efficiency is typically around 60-70% under optimal conditions, as it converts the chemical energy of ammonia into electrical energy. Factors such as temperature, pressure, and the specific design of the fuel cell can influence actual performance, but these theoretical limits provide a benchmark for efficiency.
What is true about an electrolytic cell?
A.Oxidation occurs at the anode.B.Reduction occurs at the cathode.C.Electrical energy is converted to chemical energy.The negative terminal of the voltage source is attached to the cathode.
Is there a step by step guide to constructing a microbial fuel cell available?
Yes, there are several step-by-step guides available for constructing a microbial fuel cell (MFC). These guides typically outline the necessary materials, such as electrodes, a container, and a microbial culture, as well as detailed instructions on assembling the components, preparing the culture, and optimizing the conditions for electricity generation. Many resources, including academic papers, DIY science websites, and educational videos, provide comprehensive instructions for building an MFC at home or in a laboratory setting.
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.
What is the electrolyte in hydrogen-oxygen fuel cell?
potassium hydroxide
What is the electrolyte in the hydrogen-oxygen fuel cell?
The electrolyte in a hydrogen-oxygen fuel cell is typically a proton exchange membrane (PEM) made of a solid polymer material that allows protons to pass through while preventing the mixing of the hydrogen and oxygen gases. This membrane plays a critical role in separating the two gases and facilitating the transfer of protons during the electrochemical reaction that produces electricity.
What is the fuel used in a fuel-cell automobile?
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Why is cell membrane differentially permeable?
Selective (or differential) permeability allows the cell to regulate its internal environment and maintain internal homeostasis. This is also the basis by which a neuron (nerve cell) can 'fire' and send a message along its axon - it selectively allows one electrolyte then a different electrolyte to flow across its cell membrane and change the electrochemical gradient.
Which electrolyte flows into the cell to initiate depolarization?
potassium The answer of potassium is dead wrong. Sodium is the electrolyte that flows into the cell to initiate depolarization. Potassium flows into the cell during repolarization.
What are the applications of polymers in medical field?
The chemistry industry is working on new uses for polymers as well. In development are conductive polymers for printable electronics. Polymer Electrolyte Membrane, PEM, (or Proton Exchange Membrane) fuel cells are already in use in hydrogen fuel cell vehicles. The industry is also working on materials for advanced fuel cells including a polymer electrolyte fuel cell (PFC).
What is the advantage of the presence of on cell membranes?
the membrane has a greater surface area for an increased rate of diffusion
Does peptidoglycan lack a membrane enclosed nucleus?
Well...technically yes. It should be taken into consideration that peptidoglycan is a polymer that a bacterial cell wall is composed of. Therefore, it is not alive and technically lacks a membrane. On the other hand, the cell on which the peptidoglycan is present lacks a membrane enclosed nucleus, thus making it prokaryotic.
What Controls what moves in and out of the cell?
Cell membrane
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
