A method detects fluid leaks within a fuel cell assembly. The method comprises (a) introducing a first supply fluid to a first fluid passage within the fuel cell assembly, wherein the first supply fluid comprises a tracer; (b) introducing a second supply fluid to a second fluid passage within the fuel cell assembly, wherein in the absence of a leak in the first fluid passage, the second fluid passage is fluidly isolated from the first fluid passage; and (c) monitoring a second fluid exhaust stream exiting from the second fluid passage and detecting when a concentration of the tracer is present within the second fluid exhaust stream.

1. A method of detecting fluid leaks within a fuel cell assembly, said method comprising:(a) introducing a first supply fluid to a first fluid passage within said fuel cell assembly, said first supply fluid comprising a first tracer; (b) introducing a second supply fluid to a second fluid passage within said fuel cell assembly, said second supply fluid comprising a second tracer, wherein, in the absence of a fluid leak between said first fluid passage and said second fluid passage, said second fluid passage is fluidly isolated from said first fluid passage; (c) introducing a third supply fluid to a third fluid passage within said fuel cell assembly, said third supply fluid comprising a third tracer, wherein, in the absence of a leak in said third fluid passage, said third fluid passage is fluidly isolated from said first and second fluid passages; (d) monitoring a first fluid exhaust stream exiting from said first fluid passage and detecting when a concentration of at least one of said first tracer and said third tracer is present within said first fluid exhaust stream; (e) monitoring a second fluid exhaust stream exiting from said second fluid passage and detecting when a concentration of at least one of said first tracer and said third tracer is present within said second fluid exhaust stream; and (f) monitoring a third fluid exhaust stream exiting from said third fluid passage and detecting when a concentration of at least one of said first tracer and said second tracer is present within said third fluid exhaust stream.
