A fuel cell includes a stack of electrolyte electrode assemblies and metal separators. Each of the electrolyte electrode assemblies includes an electrolyte and a pair of electrodes sandwiching the electrolyte between the pair of electrodes. The fuel cell includes a coolant channel. The coolant channel is formed between the metal separators that are adjacent to each other to allow a coolant to flow through the coolant channel, and has grooves. The coolant channel includes an inclined coolant channel group in which overlapping portions of the grooves facing each other are connected along flow of the coolant that is oriented diagonally inward with respect to a longitudinal direction. The inclined coolant channel group includes inclined coolant channels whose downstream ends are connected to a downstream center of the coolant channel and whose upstream ends are connected to coolant inlet manifolds.
