The present invention provides an apparatus and methods for variably supplying power from a stand-alone fuel cell power supply system including a power conversion unit, a power switching unit and a load control unit. Preferably, a controller manages system configuration to switch the loads, the power conversion and the delivery between the two without reducing capacity by redundantly backing up each individual portion with a bank of at least two modules for each unit. Preferably, controller actuated devices are triggered automatically in response to monitors that sense performance operating parameters and detect values operating outside a threshold range. Preferably, each of the units and the components in each unit are banked in a plurality of modular units so that individual converters may be interchanged, individual fuel cells may be interchanged, individual controllers may be interchanged, and individual storage units such as batteries may be interchanged to ensure proper operation of each bank despite changes or failures in individual components of the bank. The power system may include couplers for connecting the system to dedicated outlets such as an NEC standard 120/240 volt building circuitry. The invention monitors multiple elements from fuel supply, fuel cells, converters, storage units, and controls as well as the loads for balanced, reliably robust, high power quality, and independent power supply.

The adhesive is implemented by photocuring adhesive while the intermediate member is formed of a material transparent for light. The intermediate member is free from coloring and deformation when illuminated by light for curing the adhesive. The adhesive is prevented from dropping or turning round to other portions during assembly.
