| 发明名称 | Cathode channel shutoff in a fuel cell | ||
| 摘要 | In at least one embodiment, a fuel cell comprising a cathode flow field and a strip is provided. The cathode flow field plate defines a plurality of cathode channels for receiving a first fluid from a cathode source when the fuel cell is in an operational state. The strip includes a flexible first portion positioned about the plurality of cathode channels, the flexible first portion for moving toward the plurality of cathode channels to prevent a flow of the first fluid therein when the fuel cell is in an inoperative state. | ||

| 主权项 | 1. A fuel cell comprising: a cathode flow field plate defining a plurality of cathode channels therein for receiving a first fluid when the fuel cell is in an operational state; a membrane electrode assembly (MEA) positioned about the cathode flow field plate and proximate to an anode flow field plate; and a strip including a flexible first portion positioned about the plurality of cathode channels, the flexible first portion being moveable toward the plurality of cathode channels to prevent a flow of the first fluid therein and through the MEA when the fuel cell is inoperative. | ||
