Zusammenfassung:	The present invention relates to fuel cells that incorporate seal means, in particular seal means for sealing a bipolar plate to a membrane in a PEM fuel cell stack. The resulting fuel cell stack exhibits superior leak resistance and reduced ion leaching in water. La présente invention concerne des piles à combustible qui comprennent des moyens d'étanchéité, en particulier des moyens d'étanchéité pour sceller une plaque bipolaire sur une membrane dans un empilement de piles à combustible PEM. L'empilement de piles à combustible ainsi obtenu présente une résistance aux fuites supérieure et une lixiviation ionique réduite dans l'eau.
