electrical energy is en#ironmentally friendly" !uel cells are designed to be charged reactant isconsumed where the fuel cell to produce electricity and supply of hydrogen fuel and oxygen fromthe outside" !uel cell is classi%ed as a power plant for Semar )adranaya because fuel cells canoperate continuously or as long as there is a fuel supply and oxidant" Semar )adranaya usesroton 1xchange 4embrane (14 type of !uell /ell" &he membrane is a thin layer of solidelectrolyte separator which ser#es the cathode and anode" &his membrane is selecti#ely controlthe transport of protons from the anode to the cathode in a fuel cell" 14 catalyst containingplatinum ( t " $n addition, the fuel cell does not use corrosi#e .uids such as other types of fuelcells" -ydrogen as a fuel is consumed at the anode , producing electrons that are drawn to thecathode through the external circuit " -ydrogen ions enter the electrolyte solution and dispersedto the cathode by elektroosmotik .ow " At the cathode , oxygen is combined with the .ow ofelectrons and protons from the electrolyte to produce water and heat " $onic li+uids fuel cell ( $5!s
