More leverage isn't the answer. You could increase the leverage by puting a long pipe over the wrench handle and then pulling on the pipe. However, that is likely to damage the tool.
The problem is that the aluminum crank and the steel pedal pin have fused together. It is a phenominon that occurs when aluminum and steel are placed together. It is a real bugger to get off. When this happens with seat posts WHEW BROTHER, do you have a mess on your hands. However, with pedals you have a reasonable chance at making it happen.
Good luck. Let us know how it goes.
