Car manufacturer Nissan has unveiled its first in-house fuel cell stack, in addition to a new high-pressure hydrogen storage system.

Nissan hopes that the new technologies will help improve the performance of fuel cell vehicles and boost acceleration and driving ranges.

The company is to begin extensive testing of the new fuel cell stack over the coming months to help continued improvement in its overall performance and reliability.

The new fuel cell stack uses a thin separator to divide the hydrogen and oxygen gases supplied to the individual cells and then transfers the electricity produced to the next cell.

Nissan expects the new stack to be around 60 per cent smaller than previous fuel stacks but will be capable of delivering similar levels of power.

The newly developed high-pressure hydrogen storage cylinder will increase hydrogen storage capacity by approximately 30 per cent without any change to the cylinder's overall dimensions.
