A cooling system for a vehicular fuel cell utilizes packet pumps to electrically isolate the fuel from a grounded radiator. Fluid in a packet pump is transported from an inlet port to an outlet port in discrete packets. Because these packets are physically separated from one another, electricity does not flow through the fluid from the inlet port to the outlet port. Packet pumps include peristaltic pumps and external gear pumps.
