Abstract: A method for forming a metal electrode and a method for manufacturing semiconductor light emitting elements include providing a substrate having a semiconductor layer formed thereon; forming a bonding metal layer and a reflective metal layer on the semiconductor layer; and forming a metal electrode by layer inversion of the bonding metal layer and the reflective metal layer through a heat treatment process. An interface characteristic between a semiconductor layer and an electrode having a reflective metal layer is enhanced by a layer inversion phenomenon. High reflectivity can be obtained, because a reflection metal layer is uniformly distributed on a semiconductor layer. Further, out-diffusion of a reflective metal layer is prevented through layer inversion to enhance the thermal stability of an electrode. And the number of accepters for generating holes is increased through heat treatment under an oxygen atmosphere, so that contact resistance can be lowered.

Abstract: The disclosed is a density sensing device of a fuel cell system and a fuel cell system having the density sensing device. The density sensing device includes a density sensor that includes a collision sensor and a variable resistor coupled to the collision sensor. The collision sensor is dipped into a fuel solution, and the collisions of molecules of the fuel solution are detected in the collision sensor.

The sensor driver can be a piezoelectric member that is attached to the collision sensor. The collision sensor vibrates together with the piezoelectric member when a driving signal is applied to the piezoelectric member, which improves the accuracy of the measurement of the density.
