Types of Bladders
Fuel cells come in a variety of materials and styles depending on the intended application.  Most, if not all, can be categorized into three
types.
Type 1
These are traditionally soft-resin bladders with no external seams.  They consist of woven
ballistic-nylon cloth, or similar fabric, that is wrapped around a mold and coated with a liquid
resin that undergoes a chemical change to become a flexible solid.  Once dry, the bladder is
"smooth" with all seams contained under the resin coating.  This process gives the Type 1 high
tolerances for abrasion and direct impact, making them the strongest and most durable of all
bladder types.
Type 2

Similar to Type 1, these are soft-resin bladders with external seams.  These cells are made of a
cloth that is already impregnated with a soft-resin and is cut and wrapped around a mold and
either glued or microwaved together.  Because of this process they do not have the same
abrasion resistance as a Type 1, making them best utilized for road racing applications.

Cons:
- Applications are limited to road racing
- Not as durable as a Type 1
Pros:
- Cheapest of all types
- Prone to leaking
