A bus plate unit is provided. The bus plate unit electrically connects a unit stack for a fuel cell having a (+) and a (−) stack terminal at both sides. The unit includes a (+) bus plate having a first end portion bent toward a first side surface of the unit stack and electrically coupled to a (+) stack terminal of the unit stack. A second end portion has a (+) bus terminal and abuts an upper first side of the unit stack. A (−) bus plate has a first end portion bent toward a second side surface of the unit stack and electrically coupled to the (−) stack terminal of the unit stack. A second end portion provides a (−) bus terminal and is proximate to the upper second side of the unit stack. An insulating layer encloses a surface of the (+) bus plate and the (−) bus plate.
