The present invention relates to a fuel cell waste heat recovery system using an adsorption-type refrigeration cycle, which recovers low-temperature waste heat having a low exhaust temperature, such as a polymer electrolyte oxide fuel cell (PEFC) mainly used especially in a fuel cell vehicle among technologies recovering waste heat generated from a fuel cell. To this end, the fuel cell waste heat recovery system using an adsorption-type refrigeration cycle, which enables low-temperature waste heat recovery, comprises: an adsorption-type cycle system which is composed of an adsorption unit adsorbing waste heat of low-temperature exhaust gas emitted from a fuel cell to an adsorbent, a desorption unit desorbing waste heat, a condenser of a liquid acquisition unit, a vaporizer of a cold and heat generation unit, and a connection unit connecting the condenser and the vaporizer; and a coolant valve which connects the adsorption-type cycle system to a fuel cell cooling circuit. Accordingly, the present invention can reduce the energy consumption of a fuel cell vehicle and improve fuel cell efficiency.

    본 발명은 연료전지에서 발생하는 폐열을 회수하는 기술 중에 특히 연료전지 자동차(fuel cell vehicle)에 주로 사용되는 고분자 전해질 연료전지(pefc,polymer electrolyte oxide fuel cell)와 같은 배기온도가 낮은 저온의 폐열을 회수하는 시스템에 관한 것으로, 저온의 폐열회수가 가능하게 한 흡착식 냉동사이클 이용한 연료전지 폐열회수 시스템에 관한 것이다.이를 위해, 본 발명에 따른 연료전지의 폐열회수 시스템은 연료전지에서 배출되는 저온배기가스의 폐열과 흡착제에 흡착시키는 흡착부와 탈착시키는 탈착부와 액수취득부의 응측기와 냉열생성부의 기화기, 응축기와 기화기를 연결하는 연결부로 구성된 흡착식 사이클 시스템과, 이 흡착사이클 시스템과 연료전지 냉각회로를 연결하는 냉각회로와 냉각수 밸브로 구성되어 이루어진 것을 특징으로 한다.
