Fuel cell

A fuel cell disclosed in this specification is provided with a fuel cell stack, a fuel pipe for supplying fuel to the fuel cell stack, and a pressure sensor for measuring the pressure inside the fuel pipe. The fuel pipe is provided with an outer pipe and an inner pipe inserted through the outer pipe. A gap between the outer tube and the inner tube is sealed at two locations in the longitudinal direction of the fuel tube. Between the two portions, a first through-hole is provided in the upper portion of the outer tube, and a second through-hole is provided in the lower portion of the inner tube. A pressure sensor is attached to the first through hole. 本说明书公开的燃料电池具备燃料电池组、向燃料电池组供给燃料的燃料管、以及测量燃料管内的压力的压力传感器。燃料管具备外管、和插通于外管的内管。在燃料管的长边方向的两个部位将外管与内管之间的缝隙密封。在两个部位之间，在外管的上部设置有第1贯通孔，在内管的下部设置有第2贯通孔。在第1贯通孔安装有压力传感器。
