Fuel cell stack and switching arrangement for a fuel cell stack

摘要

A switch assembly for selectively enabling current flow through a segment of a fuel cell stack. The switch assembly includes a first plate including a first non-conductive substrate having a first conductive path therethrough and a second plate including a second non-conductive substrate having a second conductive path therethrough. A first switch is disposed between the first plate and the second plate and is in electrical communication with the first conductive path and the second conductive path. The first switch is operable in an open mode to prohibit current flow between the first conductive path and the second conductive path. The first switch is operable in a closed mode to enable current flow between the first conductive path and the second conductive path.
