It varies. Electrodes can be made of iron, carbon, platinum or any number of electrical conductors.

What is Pt electrodes?
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
What are the Types of ion selective electrodes?
There are several types of ion-selective electrodes including glass membrane electrodes, liquid ion-exchange electrodes, solid-state ion-selective electrodes, and gas-sensing electrodes. Each type is designed to selectively detect and measure specific ions in a solution based on their electrochemical properties.
What is oxidized in galvanic cell made with silver and nickel electrodes?
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
Why don't the electrodes of a fuel cell deteriorate the way the electrodes of a battery do?
The electrodes of a storage battery, particularly the lead - lead dioxide batteries commonly used in starting vehicles, may deteriorate because the discharge reaction requires one or both of the solid electrodes used to dissolve partially in the electrolyte, and the recharging reaction requires depositing new solid on both electrodes from the electrolyte. In order to maximize the possible output of electric current from a battery during the discharge or working phase, the electrodes have special surface characteristics that maximize their effective surface area. Both the charging and discharging phases of use of a battery of this type often decrease the effective surface area of the solid electrodes, and the recharging in particular may deposit solid on one or both of the electrodes in a shape that causes it to short to the other electrode. This does not occur in fuel cells, because the solid electrodes of a fuel cell do not dissolve during use. Instead, the electrodes serve (1) as catalysts to promote the oxidation and reduction reactions of fuels supplied to the electrodes as liquids or gases dissolved in the electrolyte and (2) to accept or furnish the electrons needed for the reactions to occur at separate locations. Furthermore fuel cells never need recharging, because the reactants consumed are replenished from outside the fuel cell itself and not regenerated within the cell, as for a storage battery.

What is the anode of galvanic cell made with zinc and alumminum?
Two electrodes in electrolyte solutions
What effects on welds made with damp electrodes include?
porosity
Is there types of electrodes in Shielded Metal Arc Welding?
Probably more than there are types of metal. There are many electrodes manufactured just for welding steel and for welding ON steel. Some electrodes are made to weld steel and other metals (multi-purpose). Some electrodes are designed to protect steel from chemicals and corrosive elements and are used to CLAD or OVERLAY or BUTTER. Steel, stainless steel and some other metals are manufactured with different alloys and electrodes are made to match these. Some electrodes are made to join dissimilar metals, say steel to stainless steel or Monel. It is very important to use the correct electrode for the application at hand.

What are vacuum tubes made of?
Vacuum tubes are typically made of glass or metal. The glass or metal envelope contains electrodes and is evacuated to create a vacuum inside. The electrodes are made of elements like tungsten or molybdenum.
