An electrochemical cell is a device that converts chemical energy into electrical energy through redox reactions, and it can function in both galvanic (battery) and electrolytic modes. A fuel cell, on the other hand, is a specific type of electrochemical cell that continuously converts the chemical energy of a fuel (usually hydrogen) and an oxidant (like oxygen) into electricity, water, and heat, as long as fuel is supplied. In essence, while all fuel cells are electrochemical cells, not all electrochemical cells are fuel cells; the latter has a continuous reactant supply and often operates at higher efficiencies.

What is the basic difference between solar cells and fuel cells?
A fuel cell is an electrochemical energy conversion device whiles a solar cell is a device that converts photons from the sun into electricity.
How does hydrogen fuel cell differ from electrochemical cell?
A hydrogen fuel cell is a type of electrochemical cell that produces electricity by combining hydrogen and oxygen to generate power. The key difference is that in a hydrogen fuel cell, the reactants (hydrogen and oxygen) are continuously supplied externally to sustain the electricity generation process, while in a typical electrochemical cell, the reactants are contained within the cell and eventually get depleted.
How is a fuel cell different from a typical cell?
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
Does potato power technically count as a fuel cell because of its electrochemical processes and solid fuel source?
Potato power does not technically count as a fuel cell because of its electrochemical processes and solid fuel source.
What is a biological fuel cell?
A biological fuel cell is another term for a microbial fuel cell, a bio-electrochemical system which drives a current by mimicking bacterial interactions found in nature.
What is a type of cell where chemical energy is converted into electrical energy?
A type of cell where chemical energy is converted into electrical energy is a fuel cell. Fuel cells generate electricity through an electrochemical reaction between a fuel (such as hydrogen or natural gas) and an oxidizing agent (typically oxygen).
Can the metal plates in an electrochemical cell be made of the same metal?
Historically, no, each metal has its own redox potential and it is the difference between them that causes the flow of electrons with the electrolyte carrying the charge in the cell and the circuit between the metals that carries them outside the cell. However, there are now cells that do not use the metals to create the electrochemical potentials where the metals are only conductors wherein the metals are where the electrochemical reactions take place, but are not reactants. These have to have a membrane between the two reaction compartments to keep the two reactants from reacting in solution or in the gaseous state. These are more often referred to as batteries in my opinion, or as fuel cells.

What are Electrochemical fuel cells?
Lots of things have an electrochemical cell in them. That electrochemical cell is a battery. You cell phone has at least two of them. There is a small one that "keeps alive" memory if you remove the primary battery. A flashlight has a cell or cells in it. We could go on all day. Motor vehicles have a battery, which is a collection of electrochemical cells. Note that a battery could be composed of a single cell, like the "AAA", "AA", "C" and "D" cells. We call them batteries, but they are a single electrochemical cell. A 9-volt battery, on the other hand, has several cells in it stacked in series so their voltages add. That car battery we mentioned is 6 electrochemical cells "long" so that the voltages will sum to the 12 volts (which is actually a bit over 13 volts).
Principle of operation of a fuel cell?
A fuel cell generates electricity through an electrochemical reaction between a fuel (like hydrogen) and an oxidant (like oxygen). The fuel is oxidized at the anode, releasing electrons that flow through an external circuit to the cathode, where they combine with the oxidant and protons to produce water and heat. This process generates electricity that can be used to power electrical devices.
What is the main difference between a fuel cell and a voltaic cell?
A fuel cell generates electricity from a chemical reaction between a fuel source and an oxidizing agent, without requiring any recharging. A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
What is the difference between a wet and dry hho fuel cell?
The primary difference between wet and dry HHO fuel cells lies in their operating states regarding water presence. A wet HHO fuel cell uses a liquid electrolyte, which helps facilitate the electrochemical reaction, while a dry HHO fuel cell employs a solid or membrane electrolyte, resulting in a more compact and potentially more efficient design. Wet cells can be bulkier and may require more maintenance, whereas dry cells are typically easier to handle and maintain due to their solid-state components. However, both types aim to produce hydrogen and oxygen through electrolysis for energy generation.
