Fuel cell power pack
First Claim
1. A fuel cell power pack comprising:
- (a) a gaseous hydrogen fuel cylinder;
(b) an enclosure comprising a volume for receiving the cylinder and an air duct spanning from an air inlet at one end of the enclosure to an air outlet at an opposed end of the enclosure; and
(c) an electrical generator mounted in the duct and comprising a fuel cell stack and balance of plant components arranged so that a continuous air flow path is defined in the generator that extends from the air inlet to the air outlet, and wherein at least some of the balance of plant components are located in the air flow path such that a sufficient air flow can be provided from the air flow path to supply reactant air to the fuel cell stack, and remove heat generated by the fuel cell stack and select balance of plant components.

Abstract
A fuel cell power pack comprises a base module, a ballast module, a fuel supply module, a generator module and an enclosure consisting in part of panels, that is shaped to fit within the battery bay of an electric vehicle. The base and ballast modules are configured to provide ballast for the electric vehicle, to hold the fuel supply module, and to form part of the power pack enclosure. The fuel supply module comprises a fuel storage cylinder and a length-minimized fuel supply assembly to provide a maximized fuel supply to the generator module. The generator module comprises a fuel cell stack and balance of plant components operable to generate electricity. An explosion dissipation structure is provided on at least one enclosure panel.
