A fuel cell generator apparatus and method of its operation involves: passing pressurized oxidant gas, (O) and pressurized fuel gas, (F), into fuel cell modules, (10 and 12), containing fuel cells, where the modules are each enclosed by a module housing (18), surrounded by an axially elongated pressure vessel (64), where there is a purge gas volume, (62), between the module housing and pressure vessel; passing pressurized purge gas, (P), through the purge gas volume, (62), to dilute any unreacted fuel gas from the modules; and passing exhaust gas, (82), and circulated purge gas and any unreacted fuel gas out of the pressure vessel; where the fuel cell generator apparatus is transpatable when the pressure vessel (64) is horizontally disposed, providing a low center of gravity.

A contact-based microdispensing tool for delivering extremely minute globules of epoxy material to repaired sites on high circuit density modules. The tool includes a solid probe integrally mounted in a contact sensor assembly incorporating an air-levitated core of a linear voltage differential transducer. The levitated core and the probe connected thereto are supported in neutral equilibrium by an air bearing assembly. As the assembly probe is brought into contact with one of the sites, the globule flows upon the site, the equilibrium is disturbed and a signal is produced by the transducer to halt movement of the probe relative to the site.
