Abstract
In order to improve usability of hybrid or fully electric aircraft, a fuel cell having improved efficiency and increased volume/weight specific energy density is provided. The fuel cell has a self-supporting membrane structure that is formed as a triply periodic level surface, which separates a first cavity supplied with gaseous fuel from a second cavity supplied with gaseous oxidizer in a gas-sealed manner while connecting the cavities in an ion-conductive manner.
Claims17
A fuel cell for a fuel cell system wherein the fuel cell comprises a self-supporting membrane structure, wherein the membrane structure ion-conductively connects together a first open-pored cavity and a second open-pored cavity and separates them from one another in a gas-tight manner, wherein the first cavity and the second cavity are mutually penetrating.
A method of using a triply periodic level surface shape as a membrane structure of a fuel cell, comprising the membrane structure ion-conductively connecting together a volume which can be loaded with fuel and a volume which can be loaded with oxidation agent and separates them from one another in a gas tight manner.
