Abstract

A vehicle-mounted cell stack system includes a cell stack that comprises a plurality of laminated power generating cells, and power collecting plates that sandwich both outermost power generating cells, electric wires connected to the power collecting plates, and an electric load connected to the power collecting plates via the electric wires and configured to be activated by electric power that is supplied from the cell stack. The electric wires are connected to the power collecting plates in a direction other than a cell laminating direction.

First claim

The invention claimed is:

1. A vehicle-mounted cell stack system, comprising:
a cell stack that comprises a plurality of laminated power generating cells, and power collecting plates that sandwich both outermost power generating cells;
electric wires connected to the power collecting plates;
an electric load connected to the power collecting plates via the electric wires and configured to be activated by electric power that is supplied from the cell stack; and
a cell voltage monitor case (CVM case) that is superimposed on the cell stack and houses a cell voltage monitor for monitoring a voltage of each of the power generating cells,
wherein the electric wires are connected to the power collecting plates in a direction other than a cell laminating direction, and
the CVM case comprises electric wire insertion spaces that are surrounded by partition walls and are isolated from the cell voltage monitor.

2. The vehicle-mounted cell stack system according to claim 1 , further comprising:
a PDM case that is superimposed on the CVM case and houses a power delivery module for managing electric power that is generated in the vehicle-mounted cell stack system.

3. The vehicle-mounted cell stack system according to claim 2 , further comprising a gasket that is interposed between the CVM case and the PDM case,
wherein the PDM case is fixed to the CVM case.

4. The vehicle-mounted cell stack system according to claim 2 , further comprising a power shut-off relay that is housed in the PDM case,
wherein the electric wires are connected to the electric load via the power shut-off relay.

5. The vehicle-mounted cell stack system according to claim 1 , wherein lamination surfaces of the power generating cells are parallel to a fore-and-aft direction of a vehicle and a vertical direction of the vehicle.

6. The vehicle-mounted cell stack system according to claim 1 , wherein the electric wires are connected to the power collecting plates from a top of each of the power collecting plates.

7. The vehicle-mounted cell stack system according to claim 1 , wherein the electric wires are connected to the power collecting plates in a direction that is perpendicular to longitudinal sides of the power generating cells.

8. The vehicle-mounted cell stack system according to claim 1 , wherein the electric wires are formed integrally with the power collecting plates.

9. The vehicle-mounted cell stack system according to claim 1 , wherein the cell stack is accommodated in an engine compartment that is a space in front of a cabin.
