摘要： In a fuel cell assembly, nickel-based anodes are readily oxidized when exposed to oxygen as may happen through atmospheric invasion of the assembly during cool-down following shutdown of the assembly. Repeated anode oxidation and reduction can be destructive of the anodes, leading to cracking and failure. To prevent such oxygen migration, check valves and oxygen getter devices containing oxygen-scavenging material such as metallic nickel are provided in the reformate passageways leading to and from the anodes. The check valves preferably are closed by gravity. Oxidation of the oxygen-gettering material is readily reversed through reduction by reformate when the assembly is restarted.

摘要： An energy conversion system is provided having a reformer device and a fuel cell device which is arranged behind the reformer device, the reformer device has at least one fuel feeding pipe and one air feeding pipe. The reformer device includes a reformer, wherein a reformate heat exchanger is arranged between the reformer and the fuel cell device. The reformate heat exchanger transfers heat from the hot reformate gas to a fluid in a fluid circulation system.
