Abstract

L'invention concerne un combustible destiné à être utilisé dans un dispositif de pile à combustible et comprenant un mélange de composés d'hydrocarbures qui se présente sous la forme d'un gaz à températures normales et qui contient des composés saturés dans une proportion de 60 % molaire ou plus, des composants d'oléfine dans une proportion de 40 % molaire ou plus et des composants de butadiène dans une proportion de 0,5 % molaire ou moins. Les composants saturés comportant au moins 4 atomes de carbone contiennent des isoparaffines dans une proportion de 0,1 % molaire ou plus. Le combustible présente un rendement énergétique qui est fonction de son poids et de la quantité de CO2 obtenue, une meilleure consommation de combustible, une émission de vapeurs réduite, de bonnes propriétés de manipulation telles qu'une bonne stabilité au stockage, un point d'éclair approprié et une plus faible quantité de calories requises pour le préchauffage. Par ailleurs, grâce à ce combustible, un dispositif de pile à combustible utilisant le combustible selon l'invention peut garder son rendement initial pendant une période prolongée, étant donné que ledit combustible réduit le risque de détérioration d'un dispositif de pile à combustible constitué d'un catalyseur de reformation, d'un catalyseur de conversion, d'un catalyseur de suppression de monoxyde de carbone, d'une chaîne de piles à combustible et de dispositifs analogues.
