100 amps at 100 volts is 10kw. This is a non trivial alternator. Although you can get a standard automotive alternator to put out much higher voltages than the standard 14.2v needed for charging a standard battery, most of the automotive units will fry if you try and pull much more than 1 kw to 2 kw out of them.
A few suggestions:
1) Tone down your voltage from 96 volts to 36 volts and use aircraft components. You can get some nice 28 volt 160, 200, 300, and 400 amp aircraft genertors that can be tuned up to 36 volts.

2) Most standard 120/240 generators can be rewired to give you 120 at full output, add in a bridge rectifier for $40 and you have 120DC these are likely to be a bit heavier than a 3 phase alternator.
3) Find (or have one rewound) a special purpose alterantor. Here is one that puts out 270 volt 3 phase. A good motor shop could take this and rewind it for any output voltage you want.

I am interested in building a diesel/electric micro car.
It would need 100 Amps at 100 Volts, not too far from an alternator welder.
The diesel/alternator would drive the car and it would recharge the 96 Volt battery with any excess power.
How would you suggest doing it?
The diesel would run at a constant rpm.

PS It might be a biodiesel.
