摘要: To reduce degradation of a solid polymer fuel cell during startup and shutdown, a selectively conducting component is incorporated in electrical series with the anode components in the fuel cell. The component is characterized by a low electrical resistance in the presence of hydrogen or fuel and a high resistance in the presence of air. High cathode potentials can be prevented by integrating such a component into the fuel cell. A suitable selectively conducting component can comprise a layer of selectively conducting material, such as a metal oxide.

摘要: By incorporating a selectively conducting component in electrical series with the anode components in a solid polymer fuel cell, degradation during startup and shutdown can be reduced. As a result, the startup and shutdown procedures can be simplified and consequently certain system apparatus may be omitted. The anode does not need to be rapidly purged with hydrogen on startup or with air on shutdown. Additionally, the auxiliary load usually employed during such purging is not required.
