Question

The electrode reaction that takes place at anode of ch4-o2 fuel cell is

Answer 1

Answer:

CH4 + 2H2O → CO2 + 8H+ + 8e−.

Explanation:

We get that at anode the reaction which will take takes place is as follow:- CH4 + 2H2O -> CO2 + 8H+ + 8e−.

Since, the reaction at the anode is the combustion reaction which occurs for methane that gets broken down into carbon dioxide and hydronium ions.

The reaction is occurs in the fuel cell, this reaction or the combustion reaction that is taking place in the anode of the fuel cells releases the hydronium ions along with electrons that has to be dissolved within the cells.
