<jats:p>In this paper, performance of Catalyst Coated Membrane (CCM) has been studied. Effect of various parameters on current density and power density has been analysed. Observations has been depicted using polarisation as well as power curves. CCM always gives better performance as catalyst it has direct ionic contact with membrane. CCM manufactured by Paxitech fuel cells, France has been used to perform the experiment along with stack fabricated. It is prepared with catalyst coating of 0.5mgPt/cm2 by ultrasonic spray coating method. The SEM analysis has been carried out to study morphological characteristics of CCM. Out of other parameters, hydrogen humidification and air stoichiometry have good effect on CCM performance. Maximum current density obtained was 1.28A/cm2 with hydrogen humidification temperature as 550C. The performance has been analysed by polarization curve, Description of various parameters has been given in detail.</jats:p>
