Abstract
The present invention provides a fuel cell bipolar plate and a method for manufacturing the same, in which a carbon or metal fuel cell bipolar plate is surface-treated with a complex transition metal oxide, which is a main component of a variable resistance heating element having a negative temperature characteristic, so that the bipolar plate can ensure a sufficient amount of heat, required to prevent product water from freezing, by itself in a short time without any external energy, thus improving cold start performance of a fuel cell vehicle at a temperature below zero.
