Abstract: This instant disclosure provides a fuel cell power generation system including a PSA (pressure swing adsorption) oxygen generator, an hydrogen device and a fuel cell device. The PSA oxygen generator has an oxygen storing unit for storing oxygen, and the PSA oxygen generator is for generating oxygen. The hydrogen device has a hydrogen storing unit for storing hydrogen, and the electrolysis and catalysis is for generating hydrogen. The fuel cell device is connected to the PSA oxygen generator and the hydrogen device to make electrochemical reaction of oxygen generated from the PSA oxygen generator and the hydrogen generated from the hydrogen device for outputting electrical power.

Abstract: A remote sleep quality detecting system and its method provide a portable detecting device for detecting an examinee's physical activity while the examinee is sleeping, analyzing a detected activity signal by a signal processing module to generate a statistical value, and comparing a result of the computed statistical value with a sleep state index to obtain sleep quality information, and then storing the activity signal and the sleep quality information in a storage unit. The system and method also provide a remote monitoring device including a sleep information reading module for providing a user interface, connecting the portable detecting device via the Internet and receiving the sleep quality information produced by the portable detecting device after a command from the portable detecting device is received, such that the examinee's sleep quality information can be examined from a remote location for a long term without disturbing the examinee's sleep.
