Abstract

La présente invention concerne un procédé et un dispositif permettant la production d'oxygène élémentaire ou l'augmentation de sa concentration dans l'air que respire un utilisateur. Selon le procédé, de l'eau est décomposée en hydrogène et en oxygène élémentaire grâce à de l'énergie électrique (électrolyse), l'oxygène élémentaire est mélangé à l'air respiré et l'hydrogène est mélangé à l'air extérieur pour être à nouveau converti en eau (réaction à combustible). Selon l'invention, la décomposition de l'eau en hydrogène et en oxygène élémentaire et la conversion en eau de l'hydrogène avec l'air extérieur, au cours desquelles se met en place un cycle réactionnel, se déroulent de manière simultanée et continue et sont couplées l'une à l'autre, l'énergie électrique produite lors de la conversion étant utilisée pour limiter les besoins en énergie de la décomposition. A cet effet, un électrolyseur, destiné à la décomposition de l'eau en hydrogène et en oxygène élémentaire, et une pile à combustible servant à la conversion en eau de l'hydrogène avec l'air extérieur, sont reliés électriquement et de manière à permettre l'acheminement de fluides.
