1. A fuel cell stack array comprising:
a first fuel cell stack including:
a first single cell stack structure, wherein the first single cell stack structure has a first topmost connector layer;
a first upper frame structure disposed on a top of the first topmost connector layer and having a first through-hole defined therein; and
a first lower frame structure disposed on a bottom of the first single cell stack structure;
a second fuel cell stack including:
a second single cell stack structure, wherein the second single cell stack structure has a second topmost connector layer;
a second upper frame structure disposed on a top of the second topmost connector layer and having a second through-hole defined therein; and
a second lower frame structure disposed on a bottom of the second single cell stack structure, wherein the second fuel cell stack is adjacent to the first fuel cell stack; and
a first current collector including:
a first contact inserted into the first through-hole and electrically connected to the first topmost connector layer;
a second contact inserted into the second through-hole and electrically connected to the second topmost connector layer; and
a connection portion disposed on tops of the first and second upper frame structures for electrically connecting the first and second contacts,
wherein the first current collector electrically connects the first and second topmost connector layers, and
wherein, through the first through-hole, at least 50% of a top surface of the first topmost connector layer is exposed and surface-contacts the first contact of the first current collector.
