摘要： A metal plate includes a machining subject surface. The metal plate includes a first holding portion designed to be held by a chuck and a second holding portion located at a position separated from the first holding portion and designed to be held by the chuck. The method for manufacturing the metal plate includes performing reference surface machining that machines a surface of the second holding portion that is to be held by the chuck into a predetermined shape in a state in which the first holding portion is held by the chuck. The method includes releasing the first holding portion from the chuck and holding the second holding portion with the chuck. The method also includes machining the machining subject surface in a state in which the second holding portion is held by the chuck.

摘要： An end plate has a recess extending in the horizontal direction and configured to form a flow path in which cooling water flows. Ribs are formed on the bottom surface of the recess and arranged at intervals in the vertical direction so as to extend in the horizontal direction. The cooling water flows in from the passage of a cell stack at one end in the horizontal direction of the recess. A hole that allows the cooling water to flow out is provided at the other end and at a position higher than the portion into which the cooling water flows. The inner wall surfaces of the recess spread vertically toward the hole in the portion connected to the passage. The end close to the passage of the lowermost one of the ribs is closer to the hole than the ends close to the passage of the other ribs.

摘要： An oxidation gas discharging structure is applied to a fuel cell stack that includes an end plate arranged on an end of a fuel cell body. The oxidation gas inside the fuel cell body is discharged to the outside through a through hole extending through the end plate. A slope is formed on the bottom face of the through hole to rise toward the downstream side. The slope restricts condensed water from moving downstream.

摘要： An end plate for a fuel cell stack includes a metal plate body having through-holes and inner circumference covering portions, which cover the inner circumferential surfaces of the through-holes. A part of the outer circumferential surface of the plate body that corresponds to inner ends of the inner circumference covering portions in the thickness direction is covered by an outer circumference covering portion, which is formed integrally with the inner circumference covering portions. The circumferential edge of the outer end of each through-hole is constituted by four linear portions and four arcuate portions connecting the ends of the linear portions to each other. The radius of curvature of each arcuate portion is in the range between 8 mm and 15 mm inclusive.

摘要： An end plate includes a plate body, fastening portions, and ribs. The plate body is rectangular and includes two long sides and two short sides. The plate body is arranged on an end of a cell stack of a fuel cell. The fastening portions are fastened to a case containing the cell stack. The fastening portions extend along edges of the plate body. The ribs are arranged in a grid-like manner on the plate body surrounded by the fastening portions. The ribs are arranged so that recesses defined between the ribs each have a quadrilateral shape in which two diagonals have different lengths. The ribs are arranged so that the recesses extend in a direction in which the ribs extend and so that a longer one of the two diagonals of each of the recesses extends parallel to the short sides of the plate body.

摘要： A gas-liquid separator separates water from exhaust gas discharged from a fuel cell mounted in a vehicle after the fuel cell generates electricity. The gas-liquid separator includes a case that includes a water storage region. The water storage region is located at a lowermost part in the case. The exhaust gas is introduced into the case, where water is separated from the exhaust gas. After the separated water is stored in the water storage region, the water is drained to the outside from the case. The case has in it a barrier that is formed to protrude upward to restrict water from flowing out of the water storage region when the vehicle is inclined. The barrier restricts outflow of water to the outside of the water storage region when the vehicle is inclined.
