Sid:
Your points about residential cogen systems are valid concerns. For a grid-connected system, the fuel cell or other cogen source can be sized to handle less than the peak load with additional power for peak load coming from the grid.

For a stand-alone system, you can use a smaller fuel cell and shave peaks by using batteries as storage for handling peak loads.

By reducing peaks you could size the fuel cell to handle average daily loads rather than peak loads. There would be a trade-off with the capacity and cost of the batteries. For a peak load of 10 kw you might have an average daily load of 1 to 2 kw.

As a point of comparison with a solar electric system(assuming 6 hours of peak sun per day), a 1kw fuel cell running 24 hours a day would be equivalent to 4kw of solar panels(current cost about $4000/kw, just for the panels).
