Abstract
A polysiloxane compound and a fuel cell including the same where the polysiloxane compound is an organic polymer siloxane compound containing sulfonic acid groups. By using the organic polymer siloxane compound containing sulfonic acid groups, a polymer electrolyte membrane having superior characteristics such as dimensional stability and ionic conductivity, without affecting the amount of methanol crossover, can be obtained by reducing swelling due to liquids.
